were formulated as isomeric dichlorobis(amidato)platinum(IV) species. The mixed amidenitrile species trans-[PtCl2[HN=C(OH)But)(NCBut)] (2 has also been characterized. It has NMR signals coincident with those of compound II, its space group and cell parameters are very close to those of 1, and it has a tendency to cocrystallize with 1 in the molar ratio 2:1 in favor of 2. The geometry of the amide ligands
双酰胺配合物反式-[PtCl 2 HN = C(OH)Bu t 2 ](1)是通过二氯双(叔丁基丁腈)-铂(II)的水解制备的,并通过单晶X射线衍射进行了表征。配合物在Pbcn(No. 60)空间群中随晶胞参数结晶。电池中存在十二个复杂分子,其中的三胞胎通过涉及N,Cl和O原子的分子间氢键得以稳定。该结构与先前报道的结构具有严格的相似性(DB Brown,RD Burbank和MB Robin,J。Am。Chem。Soc。,91(1969)2895)(但是,精炼显示所有非H原子并且会聚到R对于当前工作中观察到的1003个反射(F b > 6σ(F e))= 0.0471 ,而先前工作的结构分析未显示不对称单元中分子的大部分原子,并且精化收敛到R对于2047观察到的反射,其值= 0.107),建议除黄色双酰胺(1- 70%)外还包含第二种黄色物质(II。- 20%)和第三种蓝色物质(III。-
