A dinuclear complex [DyFe(CN)6(DMF)4(H2O)3]·1.25H2O(DMF=N, N-dimethylformamide) 1 based on the cyanide as linkage was prepared and structurally characterized by X-ray single-crystal structure analysis. The Dy(Ⅲ) ion is eight coordinations in a square-antiprism arrangement and the Fe(Ⅲ) ion is six coordinations oriented octahedrally. The neutral units [DyFe(CN)6(DMF)4(H2O)3] are held together by hydrogen bonds formed by lattice water molecules, coordinated water molecules and nitrogen atoms of cyanide coming from other distinct complex units to afford a three-dimensional framework.

A new lanthanumⅢ-ironⅢ complex [La(DMSO)5(H2O)](μ-CN)2[Fe(CN)4]·H2O 1 (DMSO=dimethylsulfoxide) has been prepared by a facile approach,ball-milling method,and characterized by X-ray diffraction. The crystal belongs to monoclinic,space group P21/n with a= 9.7125(3),b=21.5336(7),c=14.3804(5),β=93.242(3)o,C16H34FeLaN6O7S5,Mr=777.55,V =3002.8(2)3,Z=4,Dc=1.720 g/cm3,S=1.053,μ(MoKα)=2.278 mm–1,F(000)=1564,R= 0.0490 and wR=0.1270. The crystal structure analysis of 1 reveals a slightly distorted square-antiprism eightfold-coordinated La(Ⅲ) ion and a 1-D zigzag chain structure extending through the Fe-CN-La-NC-Fe linkages. The [La(DMSO)5(H2O)](μ-CN)2[Fe(CN)4] species are held together via hydrogen bonds to form a three-dimensional framework. 相似文献

钼铁混合金属原子簇Mo_2Fe_2Te_2(CO)_7(η~5-C_5H_5)_2是Fe_3Te_2(CO)_9与Mo_2(CO)_6(η~5~C_5H_5)_2反应所得的产物之一。它的晶体属正交晶系,空间群为Pbn2_1。晶胞参数:a=12.172(5);b=13.595(2);c=12.924(4)A,V=2138.5(2)A~3。晶体结构由直接法及差值Fourier合成解出,经最小二乘法修正,最终R因子为0.030(3233个Ⅰ>26(Ⅰ)的反射)。在簇分子中,四个金属原子呈四面体构型,两个μ_8-Te原子和一个不对称的μ_8-CO分别桥连到四面体的三个三角面的金属原子上,从而构成了缺顶点的类立方烷结构。 相似文献
