Metal Complexes with 2,2?-Dipyridylamine as Ligand: Crystal Structures of the Complexes with CdX2 (X = Cl, Br, I) and CuCN

Reactions of 2,2?-dipyridylamine (dpyam) with cadmium halides yield crystals of [Cd(dpyam)(H2O)Cl2] (1), [Cd(dpyam)Br2] (2), and [Cd(dpyam)I2] (3). With CuCl2 and KCN a complex [Cu(dpyam)CN]¡¤H2O (4) is obtained. Depending on the size of the halide ions the coordination changes from octahedral in 1 to trigonal bipyramidal in 2 and tetrahedral in 3. The coordination in 4 is trigonal. Due to the geometric strain imposed by the ligand all coordination polyhedra show significant distortions. 1 and 2 form dimers by halide bridges. With the exception of 3 all compounds form “supramolecular” structures via hydrogen bonds, e.g. chains or networks.

(matrix presented) The palladium-catalyzed N-(hetero)arylation of a number of heteroarylamines including 2-aminopyridines, 2-aminothiazoles, and their analogues has been realized using Xantphos as the ligand. Weak bases such as Cs2CO3, Na2CO3, and K3PO4 were used in most cases to allow for the introduction of functional groups. Choice of the base and solvent was critical for the success of these reactions.

The two novel silver containing complexes of N-(pyridin-2-yl)pyridin-2-amine (NDPA) molecule has been synthesized and characterized by elemental analysis, FT-Raman and FT-IR (at far and mid regions) spectroscopies. The optimized geometries of the compounds were obtained by using DFT/B3LYP method with LANL2DZ basis set for the (C10H9N3) ¡¤ AgNO3 and B3LYP method with DGDZVP basis set for the (C10H9N3) ¡¤ AgClO4. The vibrational frequencies and their IR and Raman intensities were determined by theoretical methods. In addition, the HOMO-LUMO energies, thermochemical properties and atomic charges for the complexes were obtained in same level of theory.

Synthetic Route of 499-40-1, An article , which mentions 499-40-1, molecular formula is C12H22O11. The compound – (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal played an important role in people’s production and life.

Rational design of 1-D metal-organic frameworks based on the novel pyrimidine-4,6-dicarboxylate ligand. New insights into pyrimidine through magnetic interaction

Single crystal X-ray analysis of compounds H2pmdc¡¤2H 2O (1), KHpmdc (2), and K2pmdc (3) shows that the pyrimidine-4,6-dicarboxylate (pmdc) dianion presents an almost planar geometry which confers a potential capability to act as a bis-bidentate bridging ligand, and therefore, to construct 1-D metal complexes. Based on this assumption, we have designed the first six transition metal complexes based on this ligand of formula {[M(-pmdc)(H2O)2]¡¤H2O} n [M(ii) = Fe (4), Co (5), Ni (6), Zn (7), Cu (8)] and {[Cu(-pmdc)(dpa)]¡¤4H2O}n (9) (dpa = 2,2?-dipyridylamine). The crystal structure of all of these complexes has been determined by single crystal X-ray measurements, except for compound 6 whose X-ray powder diffraction pattern reveals that it is isostructural to compounds 4-7. The bis-chelating pmdc ligand bridges sequentially octahedrally coordinated M(ii) centres leading to polymeric chains. The hexacoordination of the metal centres is completed by two water molecules in compounds 4-8 and by the two endocyclic-N atoms of a terminal dpa ligand in compound 9. Cryomagnetic susceptibility measurements show the occurrence of antiferromagnetic intrachain interactions for compounds 4-6 and 8-9 (J = -2.5 (4), -5.2 (6), -32.7 (8), and -0.9 (9) cm-1). Model calculations and analyses of the available experimental data have been used to examine the influence of several factors on the nature and magnitude of the magnetic coupling constants in pyrimidine bridged complexes, showing that metal deviation from the pyrimidine mean plane could lead to ferromagnetic behaviour.

Neutral and cationic palladium(II) and platinum(II) complexes of 2,2?-dipyridylamine with saccharinate: Syntheses, spectroscopic, structural, fluorescent and thermal studies

Four palladium(II) and platinum(II) complexes of 2,2?-dipyridylamine (dpya) with saccharinate (sac), cis-[Pd(dpya)(sac)2]¡¤H 2O (1), cis-[Pt(dpya)(sac)2]¡¤H2O (2), [Pd(dpya)2](sac)2¡¤2H2O (3) and [Pt(dpya)2](sac)2¡¤2H2O (4), have been synthesized and characterized by elemental analysis, IR, NMR, TG-DTA and X-ray diffraction. In 1 and 2, the metal ions are coordinated by two N-bonded sac ligands, and two nitrogen atoms of dpya, resulting in a neutral square-planar coordination sphere, while in 3 and 4, the metal ions are coordinated by two dpya ligands to generate square-planar cationic species, which are stabilized by two sac counter-ions. The mononuclear species of 1 and 2 interact each other through weak intermolecular N-H?O, C-H?O and pi?pi interactions to form a three-dimensional network, while the ions of 3 and 4 are connected by N-H?N and OW-H?O hydrogen bonds into one-dimensional chains. On heating at 250 C, the solid cationic complexes of 3 and 4 convert to corresponding anhydrous neutral complexes of 1 and 2 after elimination of a dpya ligand. In addition, all complexes 1-4 are luminescent at room temperature and their emissions seem to be attributed to the MLCT fluorescence.

Theoretical study on the structures and magnetic properties of metal string complexes [Ni3(L)4(NCS)2] (L = dpa?, mpta?, mdpa?, mppa?)

Density functional theory at the BP86 level and natural bond orbital theory were used to investigate the influence of bridging ligands on the Ni?Ni interactions and magnetic coupling properties of metal string complexes [Ni3(L)4(NCS)2] (L = 1: dpa? (dipyridylamine), 2: mpta? (4-methylpyridyl-thiazolylamine), 3: mdpa? (4- methyl-dipyridylamine), 4: mppa? (4-methylpyridyl-3H-pyrrolylamine)) with potential applications in molecular wires. The following conclusions can be drawn. (1) The ground states of the complexes are antiferromagnetic (AF) singlet states, which correspond to the quintet state (HS). The energy and structure of HS is similar to AF. There are three-center-four-electron sigma bonds (sigma2 sigmand1 sigma*1) along the Ni6+3 chains. (2) The Ni?Ni and Ni?N distances are unaffected by methyl substituents on the pyridine ring of dpa? ligands. However, substitution of the 3H-pyrrole ring or thiazole ring by the pyridine ring in mdpa? lengthens the N1?N2 and Ni?Ni distances but shortens the Ni2?N2 distance. These effects of the thiazole ring are weaker than those of the 3H-pyrrole ring. Therefore, the strength of the Ni?Ni interaction is 1 ? 3 > 2 > 4. (3) The predicted Jab values of 3 and 4are ?103 and ?88 cm?1, respectively. The AF magnetic coupling effects of the complexes increase with increasing Ni?Ni interaction strength: the stronger the Ni?Ni interaction, the greater the direct magnetic coupling in the sigma orbitals along the Ni6+3 chains. In addition, the stronger the Ni2?N2 interaction, the larger the indirect magnetic coupling involving the bridging ligand. The direct magnetic coupling is stronger than the indirect magnetic coupling.

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: (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal, you can also check out more blogs about499-40-1
