The title complex [La(DMSO)3(H2O)3Cr(CN)6]H2O was obtained by the reaction of LaCl37H2O, DMSO and K3[Cr(CN)6] in aqueous solution on a hot water bath. The crystal crystallizes in orthorhombic, space group P212121 with a = 9.827(3), b = 15.037(4), c = 17.633(5) ? C12H26CrLaN6O7S3, Mr = 653.48, Z = 4, V = 2605.7(13) ?, Dc = 1.666 g/m3, (MoKa) = 2.314 mm-1, F(000) = 1300, R = 0.0205 and wR = 0.0481 for 5038 observed reflec- tions (I > 2s(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.
