cationic binuclear palladium complexes of the type (μ-X)[Pd(C6F5)L2][Pd(C6F5)L′]}ClO4 (L = N or P donors) is described. X can be a pseudohalide, such as CN, SCN or N3, or a halide when L2 is a bidentate N-ligand, such as bipy. Trinuclear complexes of the type [(PPh3)2Pd](μ-X)2[Pd(C6F5)L2]2}ClO4 have only been obtained for X = CN. For X = other pseudohalide or halide, rearrangement reactions render
o-Phenylenebis(diphenylstibine) (sbsb) has been obtained from sodium diphenylstibide and o-bromophenyldiphenylstibine. The failure of other routes to this compound, and of attempts to prepare ethylenic distibines, are discussed.
Abstract Platinum metal complexes of N -methylcyclohexyl dithiocarbamate of the type [MecyhxNCS 2 ] n M [cyhx = cyclohexyl; M = Pd, Pt ( n = 2); Ru, Rh, Ir ( n = 3); Os ( n = 4)] have been synthesised. Spectral studies (IR and UV) indicate that the dithiocarbamate moiety is bidentate. From thermogravimetric (TG) curves, the order and activation energy of the thermal decomposition reaction have been
摘要 [MecyhxNCS 2 ] n M [cyhx = 环己基;N-甲基环己基二硫代氨基甲酸酯的铂金属配合物;M = Pd, Pt ( n = 2); 钌、铑、铱(n = 3);Os (n = 4)] 已合成。光谱研究(IR 和 UV)表明二硫代氨基甲酸酯部分是双齿的。从热重 (TG) 曲线可以阐明热分解反应的顺序和活化能。活化能的变化已经在硬酸碱和软酸碱(HSAB)理论的基础上进行了解释。根据差热分析 (DTA) 曲线,计算出反应热。
