Abstract

The compound previously formulated as (π-C5H5)Fe(CO)2Sn(Ph)(OSOPh)(OH) has been shown, by X-ray analysis, to be a centrosymmetric dimer with two five-co-ordinate tin atoms linked by a dihydroxo-bridge. The Sn–O bond lengths are 2·054(2)A and the O–Sn–O and Sn–O–Sn bond angles are 70·8(1) and 109·2(1)°, respectively. The Sn–Fe bond distance of 2·499(1)A is ca. 0·03 A longer than the limiting value for this bond type and is presumed to be a σ-bond. Other bond distances of interest are Sn–O(non-bridging) 2·206(2), Sn–C 2·146(3), Fe–C(carbonyl) 1·765(4), Fe–C(ring) 2·093(4), CO 1·142(5), S–O 1·539(3), SO 1·499(3), and S–C 1·808(4)A.Crystals of the dimer are monoclinic with cell dimensions a= 9·698(2)b= 18·097(3), c= 13·516(4)A, β= 123·44(3)°, space group P21/c, and Z= 2. The structure analysis, based on 2592 independent intensities measured by counter diffractometry, was carried out by the heavy-atom method and refinement was by least-squares techniques to a final R of 0·024.
配位配合物中的金属-金属键。二[(苯磺酸)-µ-羟基苯基锡]-四羰基二π-环戊二烯基二铁的晶体和分子结构
x射线分析表明,先前分子式为(π-C5H5)Fe(CO)2Sn(Ph)(OSOPh)(OH)的化合物是由两个五配位锡原子通过二羟基桥连接的中心对称二聚体。Sn-O键长为2.054 (2)A, O-Sn-O键角为70·8(1)°,Sn-O - sn键角为109·2(1)°。Sn-Fe键距为2·499(1)A,比该键的极限值长约0.03 A,推测为σ-键。其他感兴趣的键距有Sn-O(非桥接)2·206(2)、Sn-C 2·146(3)、Fe-C(羰基)1·765(4)、Fe-C(环)2·093(4)、CO 1·142(5)、S-O 1·539(3)、SO 1·499(3)和S-C 1·808(4)A。二聚体晶体呈单斜晶型,细胞尺寸a= 9·698(2)b= 18·097(3),c= 13·516(4)a, β= 123·44(3)°,空间群P21/c, Z= 2。采用重原子法对2592个独立的反衍射强度进行了结构分析,并采用最小二乘技术进行了细化,最终R为0·024。
