摘要 用浓硫酸-甲醇为催化剂,在85-90℃反应温度下,进行二茂铁与酮或醛的非均相缩合反应,合成了标题化合物.用Al_2O_3色谱柱提纯,苯加石油醚培养晶体.晶体在CAD-4四园衍射仪上MoK_α射线收集衍射数据,PDP11/44计算机上进行结构解析,结晶学数据见表1,文中对化合物的结构作了讨论. The Crystal and moleculer structure ot the title compounos was determined by x-ray analysis.Unit cell parameters and intensities were measured on a CAD-4 four-circle diffractometer.Compound(Ⅰ) Crystallizes in the monoclinic space group P^2/n with a=9.660,b=10.885,c=19.574,β=100.59°, Z=4;while compound (Ⅱ) in the monoclinic space group P^21/c with a=19.312,b=7.503,c= 20.264β=129.52°.Z=4.The structures of two complexes were solved by direct method and differeneeFourier syntheses,and refined by full-matrix least-squares with an anisotropic thermal parameters for non-hygrogen atoms,and unit weights for those reflections with I>3(Ⅰ) converged at agreement factors 0.048 and 0.051 respectively.The geometrical characteristics of two moleculars are discussed.
