Three compounds, [AsMo8V6O42][Cu(2,2-bpy)2]2[Cu(2,2-bpy)]·4H2O (1), [PMo8V6O42][Cu(2,2-bpy)2]2[Cu(2,2-bpy)]·3H2O (2) and [PMo8V6O42][Cu(2,2-bpy)2]2[Cu(2,2-bpy)]·3.5H2O
(3), have been synthesized under hydrothermal conditions and characterized by IR, UV–vis, XRD, TG, elemental analysis, and X-ray diffraction analysis. Single-crystal X-ray structure analysis reveals that 1 and 2 are isostructural and isomorphous, whereas 2
and 3 are polymorphs. Polymorphs of 1 have not been synthesized yet. The mixed-valent transition metal ion in 1–3 has been further confirmed by TG analyses. Catalytic properties of 1 and 2 have also been studied.
