title: Functionalized pentamolybdodiphosphate-based inorganic-organic hybrids: synthesis, structure, and properties.
abstract: Three inorganic-organic hybrid compounds based on functionalized pentamolybdodiphosphonopropionate anion [(HO2CC2H4PO3)2Mo5O15](4-), [Co3(bipy)4(H2O)6{(HO2CC2H4PO3)2Mo5O15}2]·(H2bipy)2·18H2O (1), [Fe3(bipy)4(H2O)6{(HO2CC2H4PO3)2Mo5O15}2]·(H2bipy)2·18H2O (2), and [Cu(bipy)(H2O)2{(HO2CC2H4PO3)2Mo5O15}]·(H2bipy)·4H2O (3), where bipy = 4,4'-bipyridine, have been successfully synthesized at different pH values in aqueous solutions. In compound 1, [(HO2CC2H4PO3)2Mo5O15](4-) acts as a tridentate ligand and coordinates to the Co(2+) ions of trimeric complex cations [Co3(bipy)4(H2O)6](6+) forming a layer. In 3 [(HO2CC2H4PO3)2Mo5O15](4-) acts as a bidentate ligand and coordinates to the Cu(2+) ions of complex chains [Cu(bipy)(H2O)2]n(2n+), forming a different layer from that in 1. The three compounds were characterized by elemental analysis, IR spectra, and TGA. In addition, their fluorescent properties and magnetic properties have also been investigated.
