摘要：
The title complex [La(DMSO)(3)(H2O)(3)Cr(CN)(6)](H2O)-H-. was obtained by the reaction of LaCl3-7H(2)O, DMSO and K-3[Cr(CN)(6)] in aqueous solution on a hot water bath. The crystal crystallizes in orthorhombic, space group P2(1)2(1)2(1) with a = 9.827(3), b = 15.037(4), c = 17.633(5) Angstrom, C12H26CrLaN6O7S3, M-r = 653.48, Z.= 4, V = 2605.7(13) Angstrom(3), D-c = 1.666 g/m(3), mu (MoKalpha) = 2.314 mm(-1) F(000) = 1300, R = 0.0205 and wR = 0.0481 for 5038 observed reflections (I > 2sigma(I)). La3+ ion is eight-coordinated by three DMSO molecules, three H2O molecules and two [Cr(CN)(6)](3-) units. The structure of the title complex possesses a cyano-bridged one-dimensional zigzag chain structure with alternating La(DMSO)(3)(H2O)(3) and Cr(CN)(6) moieties, which are linked by some hydrogen bonds to form a 3D network structure.
