Three supramolecular materials based on {P4Mo6} polyoxoanions, (Hbbi)(2)(H(2)bbi)[(Cu3Mo12O24)-O-V(OH)(6) (H2O)(6)(HPO4)(4)(H2PO4)(2)(PO4)(2)]center dot 3H(2)O (1), (Hbbi)(2)(H(2)bbi)[(Ni3Mo12O24)-O-V(OH)(6)(H2O)(2)(HPO4)(4)(H2PO4)(2)(PO4)(2)]center dot 9H(2)O (2), (HbPy)(bPY)(3)[Ni-2(H2O)(10)Na(PCA)(2)][(NiMo12O24)-O-v(OH)(6)(H2PO4)(6)(PO4)(2)]center dot 6H(2)O (3) (bbi=1,1'-(1,4-butanediyl)bis(imidazole), bpy=4,4'-bipyridine, PCA = pyridine-4-carboxylic acid), have been hydrothermally synthesized and structurally characterized by the elemental analysis, TG, IR, UV-vis, PXRD and the single-crystal X-ray diffraction. Compounds 1 and 2 exhibit covalent 1-D chains constructed from M[P4Mo6](2) dimeric cluster and {M(H2O)(n)} (M=Cu, n=3 for 1 and M=Ni, n=1 for 2) linker. Compound 3 possesses an unusual POMMOF supramolecular layers based on [Ni(P4Mo6)](2) dimeric units and 1-D metal-organic strings [Ni(H2O)(5)Na(PCA)](n), in which an in situ ligand of PCA from 1,3-bis(4-pyridyl)propane (bpp) precursor was observed. Furthermore, the electrochemical behavior of 1-3-CPE and magnetic properties of 1-3 have been investigated in detail. (C) 2014 Elsevier Inc. All rights reserved.
