摘要
A new organic-inorganic hybrid copper-substituted arsenatotungstate complex formulated as [{Cu（phen）（en）} {Cu（phen）} {Cu3（phen）3（α-AsW9033）}]（OH）·3H2O （1, en = ethylene-diamine, 1,10-phen = 1,10-phenanthroline） has been synthesized by controlling the reaction process and characterized by infrared （IR） spectroscopy, elemental analysis, and thermogravimetric （TG） analysis. Crystal data for 1： C62H56AsCusN12O37W9, Mr=3608.46, monoclinic, space group P21/n, a = 13.245（4）, b = 25.692（9）, c = 24.670（8） A, fl = 99.251（6）°, V= 8286（5） A3, Z = 4, GOOF = 1.103, R = 0.0560, wR = 0.1285. In 1, the vacant sites of the trivacant Keggin anion [α-AsW9O33]9- are occupied by three same copper coordination cations [Cu（phen）]2＋. Meanwhile, the lacunary anion [α-AsWgO33]9-, is capped by two kinds of copper coordination cations [Cu（phen）]2＋ and [Cu（Dhen）（en）]2＋, resulting in an unorecedented Dolvcation structure with Cs svmmetrv.
