摘要

标题化合物在空间群P42/n(C4h4)中结晶,Z= 8,尺寸为a=b= 19.704±0.006,c= 11.736±0.008 a。用重原子法从视觉估计的照片数据中求解出该结构,并在938个独立反射下将其细化为R 11.1%。该分子具有三明治型结构,环戊二烯环位于钼的一侧,而其他配体大致呈方形平面,位于另一侧。羰基是相互顺式的。

Crystal and molecular structure of dicarbonyl-π-cyclopentadienyliodo[tri(n-butyl)phosphine]molybdenum(II)
The title compound crystallises in the space group P42/n(C4h4), with Z= 8, in a unit cell of dimensions: a=b= 19·704 ± 0·006, c= 11·736 ± 0·008 A. The structure was solved from visually estimated photographic data by the heavy-atom method, and refined to R 11·1% for 938 independent reflections. The molecule has a sandwich-type configuration with the cyclopentadienyl ring on one side of the molybdenum, and the other ligands, which are roughly square planar, lying on the other side. The carbonyls are mutually cis.
