Hydrothermal synthesis and characterization of [Cu(phen)(VO2)(HO3PCH2CH2PO3)], a one-dimensional ribbon

The reaction of CuSO4·5H2O, Na3VO4,1,10-phenanthroline and ethylene diphosphonate in water at 180 °C for 41.5 h produces [Cu(phen)(VO2)(HPO3CH2CH2PO3)] (1) in 60–65% yield. The one-dimensional (1-D) ribbon is constructed of {V2P4O4C4} corner-sharing rings, which are further decorated and charge balanced by {Cu(phen)}2+ square pyramids.
