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.
A new lanthanum III-iron III complex [La (DMSO) 5 (H2O)] (μ-CN) 2 [Fe (CN) 4] .H2O 1 (DMSO = dimethylsulfoxide) has been prepared by a facile approach, The crystal belongs to monoclinic, space group P21 / n with a = 9.7125 (3), b = 21.5336 (7), c = 14.3804 (5) (15) = 1564, R = 0.0490 (2) 3, Z = 4, Dc = 1.720 g / cm3, S = 1.053 and μ (MoKα) = 2.278 mm-1 for C16H34FeLaN6O7S5 with Mr = 777.55 and V = 3002.8 and wR = 0.1270.
