Аннотация

Two new isostructural methoxide-bridged dimeric oxovanadium(V) complexes [VO(L1)(OMe)]2 (1) and [VO(L2)(OMe)]2 (2), where L1 and L2 are the deprotonated forms of 3-bromo- N'-[1-(2-hydroxyphenyl)ethylidene]benzohydrazide (H2L1) and 3-chloro-N '-[1-(2-hydroxyphenyl)ethylidene]benzohydrazide (H2L2) respectively, are synthesized and characterized by elemental analyses, IR spectra, and single crystal X-ray determination. Both crystals crystallize in the triclinic space group P-1. For 1, a = 7.5237(15) Å, b = 10.846(3) Å, c = 11.195(3) Å, α = 84.143(3)°, β = 72.244(3)°, γ = 77.869(3)°, V = 849.9(4) Å3, Z = 1, R1 = 0.0634, wR2 = 0.1373. For 2, a = 7.493(2) Å, b = 10.740(3) Å, c = 11.109(3) Å, α = 84.569(2)°, β = 71.783(2)°, γ = 79.822(2)°, V = 835.0(4) Å3, Z = 1, R1 = 0.0511, wR2 = 0.1076. Each V atom in the complexes is octahedrally coordinated.
