A new cyano-bridged GadoliniumⅢ-IronⅢ complex {[Gd(DMF)3(DMSO)(H2O)3](μ-CN)[Fe(CN)5]}·2H2O (DMF= N,N-dimethylformamide; DMSO=dimethylsulfoxide) was synthesized by the grinding reaction method. It crysta llizes in the triclinic, space group P1 with cell parameters: a=0.903 63(2) nm, b=1.250 78(3) nm, c=1.413 03(1) nm, α=93.174(1)°, β=94.406(1)°, γ=91.817(2)°, and V=1.588 87(5) nm3, Dc=1.582 g·cm-3, Z=2, Mr=756.72, F(000)=760,μ=2.645 mm-1. The slightly distorted square-antiprism eightfold-coordinated Gd(Ⅲ) and the approxi mately oriented octahedrally sixfold-coordinated Fe(Ⅲ) are linked by a cyano-bridge group to construct a dinuclear compound. The {[Gd(DMF)3(DMSO)(H2O)3](μ-CN)[Fe(CN)5]} species are held together via hydrogen bonds to form a three-dimensional framework. The Gd(Ⅲ)-Fe(Ⅲ) interaction is antiferromagnetic.
