摘要：
The copper-substituted tungstoantimonate(III) [Cu(En)(2)(H2O)(2)](2)[Cu(En)(2)(H2O)]{[Cu(En)(2)(H2O)](2)[Cu4Na2(H2O)(2)(OH)(2)][(alpha-SbW9O33)(2)]} center dot 3H(2)O (I) (En = ethylenediamine) has been synthesized and characterized by IR spectrum, elemental analysis, and XPS. X-ray single-crystal analyses were carried out on I, which crystallizes in the triclinic system, space group P-1, with a = 13.071(2) angstrom, b = 14.434(2) angstrom, c = 15.729(2) angstrom, alpha = 83.004(3)degrees, beta = 71.237(2)degrees, gamma = 74.787(2)degrees, and Z = 1. The title polyanion consists of two [alpha-SbW9O33](9-) trivacant moieties joined together by an annular [Cu4Na2(H2O)(2)(OH)(2)](8-) unit leading to a sandwich-type structural framework. The central belt of I contains two crystallography unique Cu2+ and four disordered Cu2+/Na+ ions which reduce the symmetry of the polyanion to C-2v.
