Triruthenium and triosmium carbonyl cluster complexes containing deprotonated di(2-pyridyl)amine in unusual coordination modes

The synthesis of the first trinuclear carbonyl clusters containing ligands derived from di(2-pyridyl)amine (Hdpa) has been achieved. Treatment of [Ru3-(CO)12] or [Ru3(CO)10(MeCN)2] with di(2-pyridyl)amine (Hdpa) gives the cluster complex [Ru3(mu-H)(mu-eta3-dpa-C,N,N)(CO)9] (1). The dpa ligand in this compound chelates a Ru atom through both pyridinic nitrogens while attached to another Ru atom through the C atom of a metalated pyridine ring, keeping the amino NH fragment uncoordinated. Curiously, the osmium compounds [Os3(mu-H)(mu-eta2-dpa-N,N)(CO)10] (2) and [Os3(mu-H)(mu3-eta2-dpa-N,N)(CO)9 ] (3), which have been stepwise prepared from [Os3(CO)10(MeCN)2] and Hdpa, contain edge-bridging (2) and face-capping (3) N-deprotonated dpa ligands coordinated through the N atom of a pyridine ring and the N atom of the original amino fragment.

A new alternating ferro- and antiferromagnetic, one-dimensional manganese(II) azide complex, [Mn(dpa)(N3)2] – Crystal structure and spectroscopic and magnetic properties

The synthesis, crystal structure, and spectroscopic and magnetic properties of a new alternating ferro- and antiferromagnetic, one-dimensional manganese(II) azide complex, [Mn(dpa)(N3)2] (where dpa is the 2,2?-dipyridylamine ligand), are reported. The compound’s crystal structure has been resolved at room temperature. The complex crystallizes in the monoclinic P21/c space group, with a = 7.089(2), b = 19.090(4), and c = 9.682(4) A, beta = 104.61(2) , and Z = 4. The structure consists of neutral chains in which each MnII cation is alternatively bridged by two end-on and two end-to-end azido bridges. The octahedral coordination of the metallic cation is completed by two dpa ligand nitrogen atoms. Reflectance measurements confirm the hexacoordination of the MnII ions in the complex. The ESR spectra at room temperature and at 4.2 K are isotropic, with a mean g-value of 2.010(1). Magnetic data were analyzed on the basis of an alternating ferro- and antiferromagnetic Heisenberg chain of MnII ions. The J-exchange parameters found are 64.3 and -75,7 K. A spin canting phenomenon has been observed in this compound, with a remnant magnetization which vanishes above 15 K. Magnetostructural correlations in manganese(II) systems of alternating magnetic sign are discussed.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 499-40-1, help many people in the next few years., Synthetic Route of 499-40-1

Structural diversity of manganese(II) complexes containing 2,2?-dipyridylamine and benzenedicarboxylates. Conformational analysis of tere-, iso- and phthalate ions: An experimental and quantum chemical approach

Four novel manganese(II) complexes with 2,2?-dipyridylamine (dipya) and various benzenedicarboxylate, BDC, ligands as anions of phthalic (pht), isophthalic (ipht) and terephthalic (tpht) acids were hydrothermally synthesized, namely, [Mn(dipya)(pht)(H2O)]2 (1), [Mn(dipya)(ipht)]n (2), [Mn(dipya)2(tpht)]n (3), and [Mn(dipya)(H2O)4](tpht) (4). All complexes were characterized by single-crystal X-ray diffraction, TG/DSC analysis and IR spectroscopy. The obtained complexes display a plenty of different structural features, including geometry of central metal atoms, BDC coordination modes and crystal packing. The coordination numbers of Mn(II) are different: 5 (in 2), 6 (in 3 and 4) and 7 (in 1). 3D networks in 1?4 are determined by strong non-covalent interactions. A survey of the Cambridge Structural Database for BDC complexes was performed in order to analyze orientation of COO groups. The energies of various BDC conformers were calculated by the second order M¡ãller?Plesset perturbation theory and three hybrid HF/DFT methods with 6-311G?? basis set. To explain different behavior, BDC ions were also examined by Localized Molecular Orbital Energy Decomposition and Natural Bond Orbital analyses. Experimental and calculated geometries are in agreement, showing that tpht and ipht anions prefer the planar conformation, while in pht anions COO groups are inclined and make complementary angles relative to the aromatic rings.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 499-40-1, you can also check out more blogs about499-40-1

pi-pi Stacking assisted binding of aromatic amino acids by copper(ii)-aromatic diimine complexes. Effects of ring substituents on ternary complex stability

Ternary Cu(ii) complexes containing an aromatic diimine (DA = di(2-pyridylmethyl)amine (dpa), 4,4?-disubstituted 2,2?-bipyridine (Y2bpy; Y = H (bpy), Me, Cl, N(Et)2, CONH2 or COOEt) or 2,2?-bipyrimidine) and an aromatic amino acid (AA = l-phenylalanine (Phe), p-substituted phenylalanine (XPhe; X = NH2, NO2, F, Cl or Br), l-tyrosine (Tyr), l-tryptophan (Trp) or l-alanine (Ala)) were characterized by X-ray diffraction, spectroscopic and potentiometric measurements. The structures of [Cu(dpa)(Trp)]ClO4¡¤2H 2O and [Cu((CONH2)2bpy)(Phe)]ClO 4¡¤H2O in the solid state were revealed to have intramolecular pi-pi interactions between the Cu(ii)-coordinated aromatic ring moiety, Cu(DA) (Mpi), and the side chain aromatic ring of the AA (Lpi). The intensities of Mpi-Lpi interactions were evaluated by the stability constants of the ternary Cu(ii) complexes determined at 25 C and I = 0.1 M (KNO3), which revealed that the stability enhancement of the Cu(DA)(AA) systems due to the interactions is in the order (CONH 2)2bpy < bpy < Me2bpy < (Et 2N)2bpy with respect to DA. The results indicate that the electron density of coordinated aromatic diimines influences the intensities of the stacking interactions in the Cu(DA)(AA) systems. The Mpi-Lpi interactions are also influenced by the substituents, X, of Lpi and are in linear relationship with their Hammett sigmap values with the exception of X = Cl and Br.

Reaction of Cu(CIO4)26H2O with cyclopentyl phosphonic acid and 2,2?-bipyridine (bpy) in presence of triethylamine afforded a trinuclear compound [Cu3(C5H9PQ 3)2(bpy)3(MeOH)(H2O)](CIO 4)2 (2). The latter dimetizes to a hexanuclear derivative [Cu6C5H9PO3)4(bpy) 6MeOH)4](CIO4) (1) under prolonged reaction conditions. Reaction of CuCI2 with cyclopentyl phosphonic acid and 2,2?-bipyridylamine (bpya) affords a tetranuclear derivative [Cu 4(C5H9PO3)2(mu-CI) 2(bpya)4](CI)2, (MeOH)2 (3). Reaction of the latter with NaCI04 also affords a trinuclear compound [Cu3(C5H9PO3)2(mu-CI) (bpya)3(H2O)](CIO4) (4).

In contrast to the above MOFs, 6 possesses a 3D network structure based on dinuclear cadmium units cross-linked by (dppa)4- and bpe ligands. For 1-6, weak hydrogen bonding and pi?pi stacking contacts link the discrete 1D chains or 2D networks to form high-dimensional supramolecular structures. Especially, in 1-6, (dppa)4- ligand displays seven different coordination modes and conformations, which may show natural synergy in the structural diversity of the resulting MOFs. The remarkable characteristic of these frameworks is that 2 demonstrates highly selective and sensitive bifunctional luminescent sensing towards acetone and Fe3+ ion. In addition, the thermal stabilities and luminescence properties of the MOFs were studied.

The crystal structure and electronic properties of a cis-distorted octahedral CuN4O2 chromophore: [Cu(dpyam) 2(OXO)]+, OXO = ONO-, O2CH – and ONO2-

The crystal structures of three bis(dpyam)copper(II) complexes, [Cu(dpyam)2(NO2)](NO2) (I) and [Cu(dpyam) 2(O2CH)](ClO4) (II) and [Cu(dpyam) 2(ONO2)](BF4) (III) have been determined by X-ray analysis. In I, the copper atom and the asymmetrically bonded nitrito group lie on a crystallographic C2-axis. The nitrito group is clearly disordered about the C2-axis giving a square pyramidal cis-distorted octahedral (4+1+1*) chromophore rather than a pseudo-regular cis-distorted octahedral chromophore. In II and III, a distortion of the cis-distorted CuN4O2 chromophore towards a square pyramidal (4+1+1*) stereochemistry is also present. The polycrystalline EPR spectra of I-III together with the high asymmetry in geometry of the CuN4O2 chromophores are suggesting that all complexes appear to be near the static distortion limit of the fluxional CuN4O2 chromophore geometry. The electronic reflectance spectra of the three complexes involve two bands at the same intensity corresponding to a cis-distorted octahedral geometry.
