Trinuclear nickel and cobalt complexes containing unsymmetrical tripodal tetradentate ligands: syntheses, structural, magnetic, and catalytic properties.
The coordination chemistries of the tetradentate N2O2-type ligands N-(2-pyridylmethyl)iminodiethanol (H2pmide) and N-(2-pyridylmethyl)iminodiisopropanol (H2pmidip) have been investigated with nickel(ii) and cobalt(ii/iii) ions. Three novel complexes prepared and characterized are [(Hpmide)2Ni3(CH3COO)4] (1), [(Hpmide)2Co3(CH3COO)4] (2), and [(pmidip)2Co3(CH3COO)4] (3). In 1 and 2, two terminal ...

The iron phosphates [C4H12N2][Fe (H2O)6](HPO4)2 (1), 3 ‘{[NH4][Fe III 2(OH)(PO4)2(H2O)]?H2O} (2) and 3 ‘{[C4H12N2][Fe III 3(PO4)3(HPO4)(H2O)]?y0.25H2O}, (3) were synthesized by hydrothermal methods and their single-crystal X-ray structures were determined. While compound 1 is only an extended hydrogen bonded network of its three ionic building blocks, compounds 2 and 3 are three-dimensional ope...
متن کاملSyntheses, crystal structures, thermal stabilities, luminescence and magnetism of two 3D pillared metal phosphonates.
Two pillared metal phosphonates: [Mn3(4,4'-bipy)(L)2].(4,4'-bipy)0.5 (1) and [Co3(4,4'-bipy)(H2O)2(L)2].(4,4'-bipy)0.5 (2) (L = O3PCH(OH)CO2), have been synthesized hydrothermally, and characterized by single-crystal X-ray diffraction along with powder XRD, EA, IR and TGA. In compounds 1-2, Mn(II) and Co(II) ions are in octahedron coordination geometries and bridged by 2-hydroxyl(phosphono)acet...
متن کاملCopper ( I ) - Purine - Phosphine Complexes . Syntheses and Molecular Structures of [
The syntheses and molecular structures of two novel polynuclear copper(I)-purine-phosphine complexes are reported. The first one is a dinuclear [Cu2(μ-HL)2(μ-dppm)(η-dppm)2] complex (H2L is 8-mercaptotheophylline). The compound crystallizes in the triclinic system, space group P1h, with cell constants a ) 12.342(5) Å, b ) 15.255(5) Å, c ) 24.972(5) Å, R ) 74.31(2)°, â ) 78.62(2)°, γ ) 72.51(2)°...
متن کاملSyntheses of difluorinated carbasugar phosphates from trifluoroethanol.
Difluorinated cyclohexene diols (prepared from trifluoroethanol) can be elaborated to racemic analogues of phosphorylated sugars via regioselective protection and phosphorylation of the exposed C-1 hydroxyl group. Cis-diol protection was achieved using stannylene methodology, though the regioselectivity depended on the orientation of the methyl group at C-5. UpJohn dihydroxylation is effective ...
