by loss of CO. Details of the structure of 2, which is structurally similar to Burlitch's recently reported Co/sub 2/(CO)/sub 6/(..mu..-CO)(..mu..-ZnCo(CO)/sub 4/)/sub 2/, will appear elsewhere. An x-ray diffraction study of crystals of a minor product showed it to be the highly unusual cluster compound 3 which can be viewed as a derivative of 2 in which the ..mu..-CO's are replaced by (..mu..-TlFe(CO)/sub
当 Fe(CO)/sub 5//KOH/MeOH 溶液用
铊盐处理时,会产生深黄棕色溶液,从中可以分离出阴离子
金属羰基络合物,建议为 (Et/sub 4/N)( Tl(Fe(CO)/sub 4/)/sub 2/)/sup 2 -/ 离子(M = Zn、Cd、Hg)。当该络合物的
甲醇溶液在室温下静置时,呈黑色结晶,2,缓慢沉积,不会再溶于
甲醇。根据分析、光谱数据和 X 射线分析,2 显示为 (Et/sub 4/N)/sub 4/(Fe/sub 2/(CO)/sub 6/(..mu.. -CO)(..mu..-Tl(Fe(CO)/sub 4/))/sub 2/)/sub 2/,由 CO 损失产生的集合体 1。2 的结构细节,其中在结构上类似于 Burlitch 最近报道的 Co/sub 2/(CO)/sub 6/(..mu..-CO)(..mu..-ZnCo(CO)/sub 4/)/sub 2/,将出现在别处。对次要产物晶体的
