| 摘要: 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。 |

| Abstract: Two new V(V) complexes, [VOL1(C2H5O)]2(1) (H2L1=2-hydroxyacetophenone salicyloylhydrazone) and [VOL2(i-C3H7O)](2) (H2L2=salicylaldehyde salicyloylhydrazone) have been synthesized and characterized by elemental analysis, IR, UV and X-Ray diffraction. Complex 1 reveals a centrosymmetric dimer, in which the two vanadium centers are bridged by phenolic oxygen atoms. Each vanadium(V) in 1 exhibits a slightly distorted octahedral geometry. While complex 2 is a mononuclear structure, in which vanadium(V) has a distorted square-pyramidal geometry. Complex 2 forms an infinite 1D chain-like supramolecular structure by intermolecular hydrogen bonds. The electrochemical property for complex 2 was studied with an electrochemical analyzer.
