Crystal Structure, Phase Transition and Thermal Behaviour of Dabcodiium hexaaquacopper(II) bis(selenate/sulfate), (C(6)H(14)N(2))[Cu(H(2)O)(6)](S(0.66)Se(0.34)O(4))(2)

Résumé

A new organically templated metal sulfate/selenate has been synthesized by the slow evaporation method and crystallographically characterized. At room temperature, the dabcodiium hexaaquacopper(II) bis(selenate/sulfate), (C(6)H(14)N(2))[Cu(H(2)O)(6)](S(0.66)Se(0.34)O(4))(2), crystallizes in the monoclinic symmetry (space group P2(1)/n) with the following unit cell parameters: a = 7.0150(2), b = 12.5810(2), c = 9.9470(2) ; beta = 90.820(1)A degrees and Z = 2. Its crystal structure is built from isolated [Cu(H(2)O)(6)](2+), (S/SeO(4))(2-) and disordered (C(6)H(14)N(2))(2+) ions linked together by a three-dimensional hydrogen-bonded network. The title compound undergoes an irreversible phase transition at 223 K on cooling run. The thermodiffractometry and the thermogravimetric analyses indicate that its decomposition proceeds through four stages giving rise to the copper oxide.
