摘　　要：将配体二烷基二硫代氨基甲酸酯(DTC)分别与三氧化钼和硝酸银在不同条件下反应得到配合物Mo[S2CN(iPr)2]4PF6(1)和Ag6[S2CN(nPr)2]6(2),采用紫外-可见吸收光谱和X射线单晶衍射对配合物1和2的结构进行表征。结果表明:配合物1和2的紫外可见谱中最大吸收峰为配体到过渡金属的特征峰(LMCT跃迁);配合物1为以钼原子为中心、周围连接8个S原子形成的十二面体结构;配合物2为由两个Ag3S3六元环组成的六核结构。Treatment of dialkl dithiocarbamate ligands with molybdenum trioxide and silver nitrate in different reaction conditions afford two complexes Mo[S2CN(iPr)2]4PF6(1)and Ag6[S2CN(nPr)2]6(2),respectively.The structures of two complexes were characterized by UV-visible absorption spectrum and single-crystal X ray crystallography.The results show that the maximum absorption peaks of complexes 1 and 2 are assigned to the LMCT(ligand-to-metal charge transfer)transition.Complex 1 is a dodecahedral structure formed by connecting 8 sulfur atoms around the center molybdenum atom,and complex 2 is a six nuclear structure containing two Ag3S3 rings.
