A Keggin-type arsenotungstate anion-supported iron-bipyridine complex, [Fe(2,2'-bipy)(3)](1.5)[(AsW10W2O40Fe)-W-VI-O-V(2,2'-bipy)(2)(H2O)]center dot 0.25H(2)O, 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 [(AsW10W2O40Fe)-W-VI-O-V(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 [(AsW10W2O40)-W-VI-O-V](5-). The complex is monoclinic, space group C2/c with a = 46.8079(13), b = 14.3990(4), c = 26.1085(8) angstrom, beta = 90.00(5)0, Z = 8, D-c = 3. 10 g/cm(3).
