N2 - The temperature dependence of the hydrothermal chemistry of the oxovanadium-phenylphosphonate/copper(II)-bipyridine system has been investigated. Reactions of identical compositions of CuSO 4ṡ5H2O, bipyridine, C6H5PO 3H2 and Na3VO4 in H2O yielded [{Cu(bpy)}VO2(O3PC6H 5)(HOC6H5)] (1), [{Cu3(bpy) 3(H2O)}V4O9(O3PC 6H5)4]ṡ3.9H2O (2ṡ3.9H 2O) and [{Cu(bpy)}VO(O3PC6H5) 2] (4) at 120 °C, 150 °C and 180-230 °C, respectively. Furthermore, variations in stoichiometry at 150 °C provided yet a fourth one-dimensional phase [{Cu(bpy)}2V3O6(O 3PC6H5)3(HO3PC 6H5)] (3). Substitution of a methyl substituent for the phenyl group yielded another one-dimensional material [{Cu(bpy)}V 2O4(O3PCH3)2ṡH 2O (5ṡH2O). The structural chemistry is discussed in terms of the polyhedral variability of vanadium oxides, the tendency of oxovanadium polyhedra to form oligomeric arrays, the variable modes of polyhedral connectivity associated with vanadium square pyramids and phosphorus tetrahedra and the steric influences of the copper(II)-bpy subunit.
