| Abstract: | A 3d-4f complex [La(DMF)6(H2O)3][Cr(CN)6]*2H2O (DMF=N,N-dimethylformamide) was prepared and characterized by single crystal structure analysis. Single-crystal X-ray diffraction analysis reveals that the present complex contains [Cr(CN)6]3- and [La(DMF)6(H2O)3]3+ ionic pairs. The La(Ⅲ) ion is nine-coordinate, and is coordinated by seven oxygen atoms of three water molecules and six DMF molecules. Each terminal CN ligand of the [Cr(CN)6]3- entity is hydrogen-bonded to oxygen atoms of the coordinated and lattice water molecules producing a three-dimensional network. Crystal data for [La(DMF)5(H2O)3][Cr(CN)6]*2H2O (C24H52CrLaN12O11=875.69): orthorhombic, space group Cmca, with lattice parameters of a=1.9346(2) nm, b=2.8902(2) nm, c=1.4825(2) nm, V=8.289(2) nm3, Z=8, S=1.074, ρcalc=1.403 g*cm-3, R1=0.046, wR2=0.117 based on 244 parameters for 5083 observed (I>2σ(I)) reflections. |
