Organoantimony(III) derivatives of the tyes RSbX2 and R2SbX in which X represents a N,N-diethyldithiocarbamate, N,N-diethylcarbamate, oximate or tropolonate ligand have been synthesized and investigated by spectroscopic (IR, UV) methods. In the RsbX2 compounds (R = phenyl, alkyl) the ligand X appears to be bidentate both in the solid state and in solution making the antimony pentacoordinate. The compounds
所述tyes的有机锑(III)衍生物RSBX 2和R 2 SBX其中X代表一个Ñ,Ñ -diethyldithiocarbamate,Ñ,Ñ -diethylcarbamate,或肟酸配体tropolonate已经合成并通过光谱(IR,UV)方法研究。在RsbX 2化合物(R =苯基,烷基)中,配体X在固态和在溶液中似乎都是双齿的,使锑五配位。化合物RSbOx 2的特殊之处在于它溶于苯或氯仿中会导致弱配位Sb 4键断裂。化合物R 2SbX(其中R =烷基)自发不成比例地变成R 3的1/1混合物SbX 2与五元配位的结果大大降低了RSbX 2的亲电反应性。相反,典型的Ph 2 SbX化合物似乎是稳定的。在固态下观察到四配位结构,但是在溶液中三配位似乎是优选的。
