摘　　要：研究了10个含氮配体的过渡金属络正离子与[Ni(cdc)_2]~2-加合物在溶液和固体状态下的电子光谱和溶液电导率,发现电导率(Ω^(-1)cm^2·mol^(-1)和加合物在HCl介质中π-π跃迁带~νmax(cm^(-1)值呈一致的变化关系.对吸收峰作出了归属,指定了负离子的MLCT带,并指出极性溶剂使MLCT带蓝移,π-π跃迁带红移.The electronic spectra and conductivities of ten adducts of transidon-metal complex cations containing nitrogen ligands with bis(N-cyanodithiocarbimato)nikelate anion in the solution and solid state have been studied, indicating the consistent change relationship between the vmax(cm-1 ) values of the π-π * transitions in the HC1 solution and the conductivities (Ω-1· cm ·mol-1 ) . Their main absorption bands and metal ligand charge transfer bands of the adducts were assigned. The solvent effect has also been observed.
