diffraction methods. Crystals of I are triclinic, a 8.028(8), b 14.561(12), c 7.961(8) Å; α 94.58(7), β 97.26(11), γ 92.23(9)° space group P. Crystals of IIa are triclinic, a 10.124(10), b 14.676(12), c 8.396(8) Å;α 95.80(8), β 111.20(10), γ 72.89(9)°, space group P. Both structures have been solved from diffractometer data by Patterson and Fourier methods and refined by full-matrix least-squares to R 0
茂镍的反应,[(η-C 5 H ^ 5)的Ni(CO)] 2和以Fe(CO)其炔烃取代的衍生物5,铁3(CO)12的铁和炔烃簇衍生物报告和讨论。已经获得相当多的新的异金属配合物:两个四核配合物的结构(η-C 5 H ^ 5)2的Ni 2的Fe 2(CO)7(I)和(η-C 5 H ^ 5)2的Ni 2 Fe 2(CO)6(C 2 Et2)(IIa)已经通过X射线衍射法测定。I的晶体是三斜晶的,a是8.028(8),b是14.561(12),c是7.961(8);α94.58(7),β97.26(11),γ92.23(9)°空间群P。IIA的晶体是三斜晶系,一个10.124(10),b 14.676(12),Ç 8.396(8);α95.80(8),β111.20(10),γ72.89(9)°,空间群P。两种结构均已通过Patterson和Fourier方法从衍射仪数据中求解,并通过全矩阵最小二乘法将其精炼为RI
