| 摘 要： | 1INTRODUCTION Recently,cyano-bridged lanthanide-transition me-tal complexes have been extensively investigateddue to their potential applications as precursors in the preparation of rare earth orthoferrites,fluores-cent and magnetic materials1].Various complexes of this system have been obtained in order to ex-plore the relations between structures and pro-perties by using different ligands,such as DMF,4,4?-bipy,and so on,to fill the coordination sites of lanthanide ions2～9].But up to…

Syntheses and Crystal Structures of Two Cyano-bridged Bimetallic Complexes [Ce(DMSO)_4(H_2O)_3Fe(CN)_6]·H_2O and [La(DMSO)_4(H_2O)_3Co(CN)_6]·H_2O(DMSO = Dimethylsulfoxide) |

| Abstract: | Two new bimetallic cyano-bridged complexes Ce(DMSO)4(H2O)3Fe(CN)6]·H2O 1 and La(DMSO)4(H2O)3Co(CN)6]·H2O 2 have been prepared by the ball milling reaction me- thod and structurally characterized by X-ray single-crystal structure analyses. Crystallographic data for 1: C14H32CeFeN6O8S4, Mr = 736.67, monoclinic, space group P21/n, a = 14.952(1), b = 13.7276(9), c = 15.392(1) A, β = 108.288(1)°, V = 2999.6(4) ·3, Z = 4, Dc = 1.631 g/cm3, μ = 2.304 mm–1, F(000) = 1480, R = 0.0593 and wR = 0.1611; and those for 2: C14H32CoLaN6O8S4, Mr = 738.54, monoclinic, space group P21/n, a = 14.945(3), b = 13.731(3), c = 15.300(3) ·, β = 107.806(1)°, V = 2989.3(11) ·3, Z = 4, Dc = 1.641 g/cm3, μ = 2.288 mm–1, F(000) = 1480, R = 0.0383 and wR = 0.1132. In both complexes the lanthanide ion is eight-coordinated in a square antiprism arrangement, and the Fe(III) or Co(III) ion in a nearly regular octahedral environment. The LnM(CN)6(DMSO)4(H2O)3]·H2O (Ln = Ce and M = Fe for 1; Ln = La and M = Co for 2) species are held together via hydrogen bonds by coordinated water molecules, lattice water molecules and nitrogen atoms of cyanide groups to form a three-dimensional framework. |
