摘要：

A new mixed valent ''Mo-W'' polyoxometallate K6Mo3W9PO40. 13H(2)O has been synthesized in the form of single crystals. The structure determination of this cubic phase (a=21.381 Angstrom) shows that it is isotypic to K5.5Na1.5PW10Cu2(H2O)(2)O-38. 13H(2)O The two structures differ by the nature of the ligands that form the Keggin units ''PMo3W9O40'' and ''PW10Cu2(H2O)(2)O-38'' respectively and by the stoichiometry and distribution of the alcaline cations located outside the Keggin units.
