英文摘要	A 3d-4f complex [La(DMF)(6)(H2O)(3)] [Cr(CN)(6)] . 2H(2)O (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)] . 2H(2)O (C24H52CrLaN12 O-11 = 875.69): orthorhombi, 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) nm(3), Z = 8, S = 1.074, rho(calc) = 1.403 g . cm(-3), R-1 = 0.046, wR(2) = 0.117 based on 244 parameters for 5083 observed (I > 2sigma (I)) reflections.; Chemistry, Applied; SCI(E); 0; ARTICLE; 5; 366-369; 20
