Synthesis and Crystal Structure of a Phenolato-bridged Dinuclear Oxovanadium(V) Complex Derived from N’-[1-(2-Hydroxyphenyl)ethylidene]-1H-indole-3-carbohydrazide
摘要:
A tridentate ligand, N'-[1-(2-hydroxyphenyl)ethylidene]-1H-indole-3-carbohydrazide (H2L), reacts with vanadyl sulfate in methanol to give a centrosymmetric dinuclear complex, [VOL(OCH3)](2). The complex was characterized by physicochemical and spectroscopic methods. The crystal of the complex is monoclinic with space group P21/c, a = 8.345(3), b = 9.469(3), c = 24.087(4) angstrom, beta = 96.290(3)., V = 1892.1(9) angstrom(3), Z = 4. X-ray crystallography indicates that each V-V atom is in a distorted octahedral coordination. The two V atoms are bridged by two phenolate O atoms, with a distance of 3.540(2) angstrom.
