Synthesis and Crystal Structure of Ni(Ⅱ) Complex with N-Salicylaldehyde-N'-phenoxyacetylhydrazine Ligand

摘要

The title complex NiL(py)3, where H2L = N-salicylaldehyde-N'-phenoxyacetyl hydrazine, was prepared and characterized by X-ray diffraction. The single crystal of the title compound, Ni(C15H12N2O3)(C5H5N)3, is of monoclinic, space group P21/c with a = 11.900(1), b = 9.6855(7), c = 23.658(2)A,β = 92.357(2)°, V = 2724.5(4) A3, Z = 4, F(000) = 1176, Dc = 1.376 g/cm3, μ = 0.753 mm-1, R = 0.0332 and Wr = 0.0820. The coordination polyhedron around the nickel atom is an elongated octahedron. The basal plane consists of one phenol oxygen, one amine carbonyl oxygen and one hydrazine nitrogen atoms from the ligand L2- and one nitrogen atom from one coordinated pyridine ligand, while the axial sites are occupied by two nitrogen atoms of two coordinated pyridine ligands.
