Synthesis, structural characterization and magnetic properties of {[Gd(DMF)3(DMSO)(H2O)3](μ-CN)[Fe(CN)5]}•2H2O

A new cyano-bridged Gadolinium(III)-Iron(III) complex {[Gd(DMF)(3)(DMSO)(H2O)(3)](mu-CN)[Fe(CN)(5)]} (.) 2H(2)O (DMF= N,N-dimethylformamide; DMSO=dimethylsulfoxide) was synthesized by the grinding reaction method. It crystallizes in the triclinic, space group P(1) over bar with cell parameters: a=0.903 63(2) nm, b=1.250 78(3) rim, c=1.413 03(l) nm, alpha=93.174(1)degrees, beta=94.406(1)degrees, gamma=91.917(2)degrees, and V=1.588 87(5) nm(3), D-c=1.592 g(.)cm(-3), Z=2, M-r=756.72, F(000)=760, mu=2.645 mm(-1). The slightly distorted square-antiprism eightfold-coordinated Gd(III) and the approximately 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)](mu-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.
