摘要A novel three-dimensional (3-D) compound [Cd4(SeO3)2Cl4(H2O)]n (1), was prepared from hydrothermal reactions and structurally characterized. Compound 1 crystallizes in the space group Fmmm of the orthorhombic system with eight formula units in a cell: a = 15.5165(4), b = 17.5090(9), c = 7.3318(5) Å, V = 1991.9(2) Å3, Cd4Cl4H2O7Se2, Mr = 863.38, Dc = 5.758 g/cm3, S = 1.075, μ(MoKα) = 16.820 mm-1, F(000) = 3088, R = 0.0427 and wR = 0.1220. Compound 1 features a 3-D structure with the cadmium atoms having two different coordination environments, i.e., six- and eight-coordination geometries. Two different chain-like structures of cadmium-oxo polyhedra are interconnect to each other to give a 2-D layer of [Cd4(SeO3)2(H2O)]n4n+. Between the [Cd4(SeO3)2(H2O)]n4n+ layers is a novel chloride layer. A 3-D framework is constructed from these [Cd4(SeO3)2(H2O)]n4n+ layers linked by the chloride layers.
