二烷基二硫代氨基甲酸基作为良好的双齿配体较易与过渡金属生成高配位的配合物,含有环戊二烯基的高配位钛、锆、铪配合物的研究相继出现,这类七配位、18-电子构型的配合物是立体化学刚性,具有独特的光谱性质和结构行为。选择钛、锆和铪二茂二氯化物与三当量的二苄基二硫代氨基甲酸钠反应合成了五种未见报道的七配位配合物,讨论了产物的光谱性质和配位结构。 Dialkyldithiocarbamates as a good bidentate ligand are more likely to form high-coordination complexes with transition metals. Studies on the highly coordinated titanium, zirconium and hafnium complexes containing cyclopentadienyl groups occur one after another The seven-coordinate, 18-electron configuration complexes are stereochemically rigid and have unique spectral properties and structural behavior. Five kinds of unreported seven-coordinated complexes were synthesized by the reaction of titanium, zirconium and hafnium dichloride with three equivalents of sodium dibenzyl dithiocarbamate. The spectral properties and coordination structure of the products were discussed.
