Abstract

In the crystal structure of the title compound, [V(2)(C(22)H(21)N(2)O(2))(2)O(4)]·2H(2)O, oxide-bridged dimers of the complex are linked to water mol-ecules by hydrogen-bonding inter-actions. The two five-membered chelate rings in the dimeric mol-ecule both adopt twist conformations. Each V(V) atom is six-coordinated by one oxide group and by two N and one O atom of the tridentate Schiff base ligand, and is bridged by two additional oxide atoms. The metal centre has a distorted octa-hedral coordination. The monoanionic ligands occupy one equatorial and two axial positions.

摘要

在标题化合物[V₂(C₂₂H₂₁N₂O₂)₂O₄]·2H₂O的晶体结构中，该配合物的氧化物桥连二聚体通过氢键相互作用与水分子相连。二聚体分子中的两个五元螯合环均采用扭曲构象。每个V(V)原子由一个氧化物基团以及三齿席夫碱配体的两个N原子和一个O原子进行六配位，并由另外两个氧化物原子桥连。金属中心具有扭曲的八面体配位。单阴离子配体占据一个赤道位置和两个轴向位置。
