2种水杨酰腙配体H2L1(H2L1=邻羟基苯乙酮缩水杨酰腙)和H2L2(H2L2=水杨醛缩水杨酰腙)分别与VO(acac)2反应,合成了2个钒配合物[VOL1(C2H5O)]2(1)和[VOL2(i-C3H7O)](2),利用元素分析、红外光谱、紫外光谱和单晶衍射等手段进行表征。配合物1是由酚氧原子桥联2个金属中心形成的具有晶体学中心对称性的双核钒(V)配合物结构,每个V(V)原子具有扭曲的八面体配位构型。配合物2为单核结构,每个V(V)原子具有扭曲的四角锥配位构型,相邻的配合物分子通过分子间氢键作用形成一维超分子链状结构。采用循环伏安法研究了化合物2的电化学性质。
Two kinds of salicyloyl hydrazone ligands, H2L1 (2-hydroxyacetophenone salicyloyl hydrazone) and H2L2 (salicylaldehyde salicylhydrazone) reacted with VO (acac) 2 to synthesize two vanadium complexes [ ] 2 (1) and [VOL2 (i-C3H7O)] (2) were synthesized and characterized by elemental analysis, IR, UV and single crystal diffraction. Complex 1 is a binuclear vanadium (V) complex with crystallographic central symmetry formed by bridging two metal centers with phenolic oxygen atoms. Each V (V) atom has a distorted octahedral coordination configuration. Complex 2 is a mononuclear structure, each V (V) atom has a distorted quadrangular pyramid coordination configuration, and adjacent complex molecules form a one-dimensional supramolecular chain structure by intermolecular hydrogen bonding. The electrochemical properties of compound 2 were studied by cyclic voltammetry.
