A novel three-dimensional(3-D) compound [Cd4(SeO3)2Cl4(H2O)]n(1) was prepared from a hydrothermal reaction 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) ,V = 1991.9(2) 3,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.
A novel three-dimensional (3-D) compound [Cd4 (SeO3) 2Cl4 (H2O)] n (1) was prepared from a hydrothermal reaction and structurally characterized. Compound 1 crystallizes in the space group Fmmm of the orthorhombic system with eight formula (4), b = 17.5090 (9), c = 7.3318 (5) , V = 1991.9 (2) 3, 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, ie, and eight-coordinated geometries. Two different chain-like structures of cadmium-oxo polyhedra are interconnected 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. The A3-D framework is constructed from these [Cd4 (SeO3) 2
