摘　　要：Two new bimetallic cyano-bridged complexes [Ln（DMSO）2（H2O）（μ-CN）4Fe（CN）2] （Ln = Ce 1, Eu 2） have been prepared by the grinding reaction method and structurally characterized by X-ray single-crystal structure analysis. Crystallographic data for 1： C10H14CeFeN6O3S2, Mr = 526.36, monoclinic, P2/n, a = 7.852（4）, b = 10.729（5）, c = 11.181（5）A,β = 96.992（8）°, V = 935.0（7） A^3, Z = 2, Dc = 1.870 g/cm^3,/1 = 3.421 mm^-1, F（000） = 512, R = 0.0363 and wR = 0.0971; and those for 2： C10H14EuFeN6O3S2, Mr = 538.20, monoclinic, P21n, a = 7.739（5）, b = 10.668（7）, c = 11.008（7） A,β = 96.943（3）°, V = 902.1（11） A^3, Z = 2, Dc = 1.981 g/cm^3,/1 = 4.499 mm^-1, F（000） = 522, R = 0.0345 and wR = 0.0855. In each complex the lanthanide ion is seven-coordinated in a pentagonal bipyramidal arrangement, and the Fe（Ⅲ） ion is in a nearly regular octahedral environment. The title complexes can be described as two- dimensional （2-D） stair-like structures, which are further connected by hydrogen bonds to form three-dimensional （3-D） frameworks.Two new bimetallic cyano-bridged complexes [Ln（DMSO）2（H2O）（μ-CN）4Fe（CN）2] （Ln = Ce 1, Eu 2） have been prepared by the grinding reaction method and structurally characterized by X-ray single-crystal structure analysis.
