摘要：
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.
