钛钼异双核配合物的合成及结构研究

Synthesis and Structure Analysis of Ti-Mo Heterobimetallic Complexes

合成了13个钛-钼异双核金属有机配合物,测定了它们的碳、氢、氮、钛及钼的含量,还测定了~1H、^(13)C、^(11)B及^(95)Mo NMR和红外、质谱、电导数据.确认该类配合物分子中存在Ti-Mo之间的金属-金属键和一个桥羰基键,并具有如下结构:其中R=H,Pz(吡唑基);R'=CH_3,OCH_3,OC_2H_5;X=H,CH_3;Y=H,CH_3.

Thirteen Ti-Mo heterobimetallic complexes were prepared.The structures of these complexes were characterized by element analysis,1H NMR,13C NMR,95Mo NMR,11B NMR,IR,MS and electrical conductivity.The heterobimetallic complexes contain metal-metal bonds with some covalent character and semibridging carbon monoxide.The common structural formula of Ti-Mo heterobi metallic complexes can be written as followWhere R=H,Pz;X=H,CH3;Y=H,CH3,R=CH3,OCH3,OC2H5.
