The syntheses of 16 vanadium(IV and V) complexes with ONO tridentate Schiff base ligands are described. The vanadium(IV) compounds were synthesized with 1,10-phenantroline as a co-ligand. In the case of five complexes of vanadium(V), the solvent molecule in form of ethanol or ethoxy ligand fill the coordination sphere of V(V) to six. In the crystal structure of selected complexes the mixture of isomers
摘要描述了16种具有ONO三齿Schiff碱配体的钒(IV和V)配合物的合成。钒(IV)化合物是用1,10-菲咯啉作为共配体合成的。在钒(V)的五种络合物的情况下,乙醇或乙氧基配体形式的溶剂分子将V(V)的配位域填充为六个。在所选络合物的晶体结构中,由于配体不对称并且在络合物中形成5元和6元环,因此在晶胞中观察到异构体以1:1比例的异构体混合物。还通过元素分析,IR和UV-Vis光谱,磁和循环伏安法测量对所有配合物进行了表征。络合物在DMSO-H2O混合物中的稳定性在pH = 7.0和2.0的条件下进行。
