T1 - Temperature dependence of the crystal chemistry of the oxovanadium- ethylenediphosphonate/copper(II)-2,2′-bipyridine system. Crystal structures of the two-dimensional [Cu(bpy)VO 2(O 3PCH 2CH 2PO 3H)]•1.5H 2O and of the one-dimensional [Cu(bpy)VO 2(O 3PCH 2CH 2PO 3H)]

N2 - Three different materials of the oxovanadium-ethylenediphosphonate/ copper(II)-bipyridine system [V/O/{(CH 2) 2(PO 3H x) 2} (4-x)-/Cu(II)(bpy)] were isolated via hydrothermal synthesis from identical starting solutions with temperatures as the only variable. The phases isolated at 120 and 230°C are both two-dimensional networks, [Cu(bpy)VO 2(O 3PCH 2CH 2PO 3H)]•1.5H 2O (1•1.5H 2O) and [Cu(bpy)VO(O 3PCH 2CH 2PO 3)] (3), respectively, while the phase produced at the intermediate temperature of 180°C is the one-dimensional [Cu(bpy)VO 2(O 3PCH 2CH 2PO 5H)] (2). Despite the unexpected absence of correlation between temperature and dimensionality, the number of Cu(II) atoms per 1000 Å 3 increases in the order 2.31:2.57:2.62 for 1:2:3, as expected.
