Abstract: The complex with the formula [CeFe(CN)6(H2O)3].2H2O was synthesized and structurally characterized. It crystallizes in hexagonal, space group P3, a=0.75320(10) nm, b=0.75320(10) nm, c=1.4374(3) nm, γ=120°, V=0.7062(2) nm3, Z=3, Dc=3.048 Mg.m-3, F(000) =606, μ=6.346 mm-1, T=293(2) K, R1=0.0169, Wr2=0.0459. The structure is a three-dimensional network containing open channels formed by the nine-coordinated CeN6(H2O)3 groups and octahedral FeC6 groups through the cyanide linkages. Magnetic susceptibility measurements in the temperature range of 5.1~300 K show an antiferromagnetic interaction between the Ce3+ and Fe3+ ions.
