(Azido-kN)bis-(di-2-pyridylamine)-copper(II) hexa-fluoro-phosphate and (azido-kN)bis-(di-2-pyridylamine)-copper(II) chloride tetra-hydrate

The two new title complexes, [Cu(N3)(dpyam)2]PF6 (dpyam is di-2-pyridylamine, C10H11N3), (I), and [Cu(N3)(dpyam)2]Cl¡¤4H2O, (II), respectively, have been characterized by single-crystal X-ray diffraction. Both complexes display a distorted square-pyramidal geometry. Each Cu atom is coordinated in the basal plane by three dpyam N atoms and one azide N atom in equatorial positions, and by another N atom from the dpyam group in the apical position. In complex (I), the one-dimensional supra-molecular architecture is assembled via hydrogen-bonding inter-actions between the amine N atom and terminal azide N atoms and the F atoms of the PF6 – anion. For complex (II), hydrogen-bonding inter-actions between the amine N atom, the Cl- anion and water O atoms result in a two-dimensional lattice.

Synthesis and structural characterization of a linkage isomer to a mononuclear Nickel(II) complex: Experimental and computational depiction of phosphoesterase efficiency

Synthesis and structural characterization of a linkage isomer, bis(2,2?-dipyridylamine)dithiocyanato(k-S)nickel(II), [Ni(dpa)2(k-SCN)2] (1) of a previously reported Ni(II) complex, [Ni(dpa)2(k-NCS)2] (dpa = 2,2?-dipyridylamine; SCN = thiocyanate) has been reported herein. X-ray structural analysis of 1 reveals that Ni(II) complex crystallizes in monoclinic system with P21/c space group and exists in trans configuration. The coordination geometry for 1 adopts a tetragonal structure. Supramolecular aspects of the Ni(II) complex indicate that N atom of SCN behaves as a donor and H atom of dpa ligand acts as a receptor in growing 1D crystalline structure along b axis in solid state. The aromatic rings in 1 prefer to exist in face-centred stacking with interplanar distance of 3.426 A and supports strongly to form self-assembled 3D crystalline architecture. Hirshfeld surface analysis further recommends this crystalline assembly in solid state. 1 exhibits promising phosphatase activity towards disodium(4-nitrophenyl)phosphate (PNPP) in aqueous-methanolic medium. The hydrolytic phosphatase efficiency for 1 is determined in terms of turnover number (kcat) as 3.38 ¡Á 104 h?1. Moreover, density functional theoretical computations closely replicate the structural parameters and spectroscopic behaviour of 1.

Two new mononuclear mixed-ligand complexes [Cu(HL)(OAc)(dipyam)] (1)¡¤H2O and [Cu(HL)Cl(dipyam)] (2)’SoIv (HL = monoanionic lactate and dipyam = 2,2′-dipyridylamine) have been synthesized and structurally characterized by X-ray diffraction. The supramolecular association in these complexes have also been analyzed. In both cases the copper(II) ion is in a slightly distorted square-pyramidal environment. The twocomplexes are extended into 3D networks, through hydrogen bonding alone in 1 and through both hydrogen bonding and pi-pi interactions in 2.

Dehydrative Glycosylation Enabled by a Comproportionation Reaction of 2-Aryl-1,3-dithiane 1-Oxide?

A new dehydrative glycosylation reaction has been established by capitalizing on the comproportionation reaction of 2-aryl-1,3-dithiane 1-oxides promoted by triflic anhydride (Tf2O). By wedding the high potency of thiophilic promoter system with the step efficiency of dehydrative glycosylation, this reagent underwent facile intermolecular oxothio acetalization with C1-hemiacetal donor to install a temporary leaving group, rendering a transient electrophilic center at the remote site to the anomeric position. The sulfenyl triflate tethered at the terminus concomitantly activated the sulfide intramolecularly to afford the oxocarbenium ion, thereby facilitating the title glycosylation. Aside from accommodating broad range functional groups and inactive hemiacetal substrates, the present activation protocol also proved expedient for 1,3-diol protection. Most importantly, this method further provided a fresh perspective for the application of sulfur chemistry to carbohydrate chemistry.

Oxidation chemistry of axially protected Mo2 and W2 quadruply bonded compounds

Reported is a facile, high-yielding one-pot synthesis of the quadruply bonded ditungsten (II,II) compound W2(dpa)4 (1) (dpa=2,2?-dipyridylamide), which was obtained from W(CO)6 at high temperature in naphthalene. A similar reaction in 1,2-dichlorobenzene furnished a ditungsten (III, III) species as the major product that was crystallized as [W2(dpa)3Cl2][BPh4] (3). The [W2(dpa)3Cl2]+ cation is better prepared by oxidation of 1 with SO2Cl2. Compound 1 was characterized by X-ray crystallography and cyclic-voltammetry, and is compared with its earlier reported molybdenum analogue, Mo2(dpa) 4 (2). One-electron oxidation products of 1 and 2, [W 2(dpa)4][BPh4] (1BPh4) and [Mo 2(dpa)4][BPh4] (2BPh4), respectively, have also been synthesized. The crystallographically determined metal-metal distances of 2.23 A and 2.14 A in 1BPh4 and 2BPh4, respectively, are in agreement with metal-metal bond orders of 3.5. Unlike most previously reported Mo25+ and W 25+ compounds, the primary coordination spheres around the M2-units in 1/1BPh4 and 2/2BPh4 remain unchanged upon one-electron oxidation, because the tridentate dpa ligand hinders axial coordination of exogenous ligands.

Synthesis and photoluminescence properties of four rhenium(I) complexes based on diimine ligands with oxadiazole/carbazole moiety

By introducing two carrier-transporting moieties (oxadiazole and carbazole) into two diimine ligands (2-(2-pyridine)-benzimidazole and 2,2′-dipyridylamine), respectively, four novel ligands (L1-L4) and their corresponding rhenium(I) complexes (1-4) have been synthesized and characterized by elemental analysis, 1H NMR and IR spectra. Their photophysical properties, thermal analysis, along with the X-ray crystal structure analysis of L4 and corresponding complex 4 are also described. In absorption spectra, the 2-(2-pyridine)-benzimidazole containing complexes 1, 2 show the intraligand charge-transfer (pi?pi*(L)) bands and metal-to-ligand charge-transfer dpi(Re)?pi*MLCT bands, while the 2,2′-dipyridylamine containing complexes 3, 4 only show the pi?pi*bands. In the excitation spectra, all the complexes show strong MLCT bands. After excitation of pi?pi*or MLCT bands, all the four Re(I) complexes exhibit broad bands around 550-560nm due to the Re(I)-based 3MLCT emission. The two complexes 1 (with oxadiazole moiety) and 2 (with carbazole moiety) show the photoluminescence quantum efficiency of 2.0% and 7.5% in solid state, respectively, indicating that the carbazole unit is the better chromophore to enhance the luminescence efficiency of diimine Re(I) complexes than the oxadiazole moiety.
