Abstract

Two new organic/inorganic composite coordination polymers have been synthesised by the reaction of cadmium (II) iodide with 1,4-dioxane, [CdI2(C4H8O2)]n (1) and with N-(2,4-dichlorobenzylidene)ethanolamine, [Cd2I4(NH2CH2CH2OH)2]n (2). These complexes have been structurally characterised by X-ray diffraction analysis. Complex 1 crystallizes in the monoclinic space group P21/c with a = 8.2028 (3), b = 14.3556(5), c = 7.6594(3) Å, β = 100.513(1)°, V = 886.80(6) Å3 and Z = 4. Complex 2 crystallizes in the orthorhombic space group Pccn with a = 8.7369(6); b = 13.2514(9), c = 14.3794(11) Å, V = 1664.8(2) Å3 and Z = 8. The crystal structure analysis shows an octahedral environment around the cadmium atom in complex 1 and the crystal packing comprises of doubly iodo-bridged polymeric layers, where the two independent 1,4 dioxane ligands act as are bridging species through O atoms. The structure of 2 is an iodo bridged one-dimensional chain with the two independent Cd(II) ions alternating along the polymer. Here one Cd(II) ion is coordinated in a slightly distorted octahedral geometry by two chelating ethanolamine ligands via O, N donors and two iodo ligands. The other Cd(II) ion is tetrahedrally coordinated by four iodo ligands.
