A new organic-inorganic hybrid copper-substituted arsenatotungstate complex formulated as[{Cu(phen)(en)}{Cu(phen)}{Cu_3(phen)3(α-AsW_9O_(33))}](OH)-3H_2O(1,en = ethylenediamine,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:C_(62)H_(56)AsCu_5N_(12)O_(37)W_9,M_r = 3608.46,monoclinic,space group P2_1/n,a= 13.245(4),b = 25.692(9),c = 24.670(8) A,β= 99.251(6)°,V= 8286(5) A~3,Z = 4,GOOF = 1.103,R= 0.0560,wR= 0.1285.In 1,the vacant sites of the trivacant Keggin anion[α-AsW_9O_(33)]~(9-) are occupied by three same copper coordination cations[Cu(phen)]~(2+).Meanwhile,the lacunary anion[α-AsW_9O_(33)]~(9-) is capped by two kinds of copper coordination cations[Cu(phen)]~(2+) and[Cu(phen)(en)]+,resulting in an unprecedented polycation structure with C_s symmetry.
