Abstract
Two new hybrid polyoxotungstates, [Co(2,2'-bipy)3][α- H5PW11CoO40]-3H2O 1 and rFe (2,2'-bipy) 3] 2 [α-HBW1 2O 40]-2. 5H20 2 (2,2'-bipy = 2,2'-dipyridyl), have been hydrothermally synthesized and characterized by IR, TGA and single-crystal X-ray structural analyses. The results of X-ray crystallography analyses exhibit that 1 consists of one cc-Keggin anion [α-H5PW11CoO 40]2 and one isolated [Co(2,2'-bipy)3] 2+ complex, while 2 is constructed from one α-Keggin anion [α- HBW11O40]4- and two isolated [Fe(2,2'-bipy)3]2+cations. The data for 1: orthorhombic system, space group Pbcn, a = 16.062(6), b = 27.278(10), c = 16.951(6) Å, V = 7427(5) Å3 and Z = 4; and those for 2: triclinic system, space group P1̄, a = 13.787(3), b = 17.857(5), c = 18.918(5) Å, α = 88.009(12), β = 72.768(10), γ = 74.935(10)°, V= 4291(2) Å3 and Z = 2.
