analysis, IR spectrum, and electrochemical measurements. The composition of metal and RL and the coordination mode, such as monodentate, chelate, and bridging or capping, depend on both the central metal ion and the substituent on the diaminocarbenium moiety. The useful criteria for the coordination mode are found to be the wavenumber of the –CS2 asymmetric stretching vibration in the solid state, and the
摘要以高氯酸金属盐与RL在EtOH或CH2Cl2中反应制得了一系列具有双(N,N-二取代氨基)二硫代羧酸碳鎓盐的12族金属配合物,并通过X射线结构分析,IR光谱,和电化学测量。金属和RL的组成以及配位方式(例如单齿,螯合物以及桥连或封端)取决于中心金属离子和二氨基碳鎓部分上的取代基。配位模式的有用标准是–CS2固态不对称拉伸振动的波数,以及溶液中基于配体的还原电势。
