Three novel heteropolyanions [PMo12Sb2O40][Cu(enMe)2]·4H2O (1), [PMo12Sb2O40][Ni(enMe)2]·4H2O (2) and [PMo12Sb2O40][Cu(en)2]·H3O·H2O (3) (enMe = 1,2-diaminopropane, en = ethylene diamine) have been synthesized and characterized by IR spectroscopy, X-ray photoelectron spectroscopy (XPS), thermogravimetric analyses and elemental analyses. Single-crystal X-ray diffraction analyses reveal that these three compounds represent the first examples of compounds based on the novel polyoxoanion {PMo12Sb2O40} and different transition metal coordination complexes. 1and 2are isostructural and both exhibit novel 1-D structures. In contrast to 1and 2, 3exhibits a substantially distinct novel 1-D structure. In addition, 3is the first example of an extended structure constructed from polyoxoanions and Cu+transition metal coordination complexes. [ABSTRACT FROM AUTHOR]
