Two new bimetallic cyano-bridged complexes [Ln(DMSO)2(H2O)(μ-CN)4Fe(CN)2] (Ln = Ce 1, Eu 2) have been prepared by the grinding reaction method and structurally characterized by X-ray single-crystal structure analysis. Crystallographic data for 1: C10H14CeFeN6O3S2, Mr = 526.36, monoclinic, P2/n, a = 7.852(4), b = 10.729(5), c = 11.181(5) (A), β = 96.992(8)°, V = 935.0(7) A3, Z = 2, Dc = 1.870 g/cm3, μ = 3.421 mm-1, F(000) = 512, R = 0.0363 and wR = 0.0971; and those for 2: C10H14EuFeN6O3S2, Mr = 538.20, monoclinic, P2/n, a = 7.739(5), b = 10.668(7), c = 11.008(7) A, β = 96.943(3)°, V = 902.1(11) A3, Z = 2, Dc = 1.981 g/cm3, μ= 4.499 mm-1, F(000) = 522, R = 0.0345 and wR = 0.0855. In each complex the lanthanide ion is seven-coordinated in a pentagonal bipyramidal arrangement, and the Fe(Ⅲ) ion is in a nearly regular octahedral environment. The title complexes can be described as two-dimensional (2-D) stair-like structures, which are further connected by hydrogen bonds to form three-dimensional (3-D) frameworks. 相似文献

The Cu(Ⅱ) atom is coordinated by five oxygen atoms, one of which from DMF is in the axial position, to form a square pyramidal geometry. That the thenoyl groups in the ligands take the cis-form around the Cu(Ⅱ) atom is explained by the hydrogen bonding effect. 相似文献

In two of the complex cations (isosaer A), HaO+ cation is anchored in each crown ether ring by three stronger hydrogen bonds. In another complex cation (isomer B) only two stronger hydronger bonds are formed between the H3O+ cation and crown ether. The third hydrogen bond is very weak. 相似文献
