Two new compounds of polyoxoanions, transition metal complexes and organic amines.

Two compounds [Cu(biim)] 2 (TEA) 2 [HPW 12 O 40 ]·H 2 O ( 1 ); [Cu(im) 2 ](im)[H 2 PMo 12 O 40 ] ( 2 ), (biim = 2,2′-biimidazole, im = imidazole, TEA = triethylamine) have been hydrothermally synthesized and characterized by IR, XPS, XRD, UV-Vis, fluorescent spectra analysis, elemental analysis, X-ray diffraction analysis, cyclic voltammetric measurement and single crystal X-ray diffraction analysis. Single crystal X-ray diffraction analysis reveals that compounds 1–2 represent new examples formed by polyoxoanions, transition metal coordination complexes (TMCs) and organic amines. Compound 1 exhibits a 3-D supermolecular structure of which layers A and C are stacked alternatively, while compound 2 first shows a 1-D chain structure with an –A↑–A↓–A↑–A↓ linking mode, then along a , b and c axis, respectively exhibits different beautiful 2-D supramolecular networks via hydrogen bond interactions.The photodegradation properties of compounds 1–2 have been investigated.
