    Abstract

    The title compound,{H2NCH2CH2NH2CH2CH2 }{Cu(H2O)6}(SO4)2, I, has been synthesized under solvo/hydrothermal conditions and their crystal structure analyzed by X-ray single crystallography. Compound I crystallizes in the monoclinic system, P21/n space group with a = 6.852(1), b = 10.160(2), c = 11.893(1) Å, β = 92.928(8)o, V = 826.9(2)Å3, Z = 2, Dx = 1.815 g/cm3, R1 = 0.031 and ωR2 = 0.084. The crystal structure of the piperazine templated Cu(II)-sulfate demonstrate zero-dimensional compound constituted by doubly protonated piperazine cations, hexahydrated copper cations and sulfate anions. The central Cu atom has a elongated octahedral coordination geometry. The crystal structure is stabilized by three-dimensional networks of the intermolecular Owater-H…Osulfate and Npip-H…Osulfate hydrogen bonds between the water molecules and sulfate anions and protonated piperazine cations. Based on the results of thermal analysis, the thermal decomposition reaction of compound I was analyzed to have three distinctive stages.
