A Keggin-type arsenotungstate anion-supported iron-bipyridine complex, [Fe(2,2'-bipy)3]1.5- [AsWVI10WV2O40Fe(2,2'-bipy)2(H2O)] · 0.25H2O, has been hydrothermally synthesized and characterized by IR and ESR spectra, TG-DTA analysis, and single crystal X-ray diffraction. Each structural unit of the title compound consists of one [AsWVI10WV2O40Fe(2,2'-bipy)2(H2O)]3− heteropolyanion, one and a half [Fe(2,2'-bipy)3]2+ cations, and a quarter of an H2O molecule. In the heteropolyanion the [Fe(2,2'-bipy)2(H2O)]2+ unit is covalently bonded to the reduced Keggin polyoxoanion [AsWVI10WV2O40]5−. The complex ismonoclinic, space group C2/c with a = 46.8079(13), b = 14.3990(4), c = 26.1085(8) Å , β = 90.00(5)°, Z = 8, Dc = 3.10 g/cm3
