Synthesis and crystal structure of a 1D chain polyoxometalate-based complex {[Cu~I(en)_2(H_2O)]_2{GeW_(12)O_(40)[Cu~(II)(en)_2]} centre do 2.5H_2O}_n

摘要

A 1-D infinite chain organic-inorganic hybrid compound, [Cu~I(en)_2(H_2O)]_2{GeW_(12)O_(40)[Cu~(II)(en)_2]} centre do 2.5H_2O} , was synthesized hydrothermally and characterized by 1R, UV spectroscopy, TG analyses, and single-crystal X-ray diffraction. Structural, analysis indicates that neighboring [GeW_(12)O_(40)]~(4-) polyanions are interconnected by [Cu(3)(en)_2]~(2+) subunits via W-O_t-Cu(3) bridges, generating a ID infinite chain structure. Furthermore, the compound shows photoluminescence in the solid state at room temperature.
