N2 - Three new inorganic-organic composite polyoxotungstates [Cu(2,2'- bpy) 2]5[aPW11.5CU0.5O 40]·2H2O 1, [Co(2,2'-bpy)2(N 3)2]4H3[α-PW 12O40]-3H2O 2 and [Cu(2,2'-bpy)2(4,4'-bpy)] 2[a-Ge W12O40]·4H2O 3 (2,2'-bpy = 2,2'-bipyridine, 4,4'-bpy = 4,4'-bipyridine) have been hydrothermally synthesized and structurally characterized. 1 crystallizes in the orthorhombic space group Pna21 with a = 27.847(3), b = 21.597(2), c = 20.1179(19) Å, V= 12099(2) Å3, Z= 4, GOF = 1.038, R = 0.0427 and wR = 0.1035; 2 belongs to the triclinic space group P1̄ with a = 12.31150(10), b = 16.1954(4), c= 19.36290(10) Å, a = 99.366(11), ß =105.168(8), γ = 111.836(8)°, V= 3309.98(9) Å3, Z = 1, GOF = 1.024, R = 0.0739 and wR = 0.2216; and 3 crystallizes in the monoclinic space group P21/n with a = 12.858(4), b = 20.943(6), c = 15.598(5) Å, ß = 102.338(5)°, V= 4103(2) Å3, Z= 2, GOF= 1.026, R = 0.0557 and wR = 0.1316. The common structural features of 1 3 are that their molecular structures all consist of a saturated α-Keggin polyoxoanion and several discrete metal-organic moieties. Intriguingly, 2 and 3 are composed of metal-organic coordination moieties with two mixed ligands.
