Abstract

The hydrothermal reaction of CuSO4·5H2O, Na3VO4, methylphosphonic acid, 2,2′-bipyridine, and H2O in the mole ratio 1.22:1.30:3.63:1.00: 2250 at 150°C for 43 h yielded β-[Cu(bpy)V2O6] (1). The structure of 1 is a one-dimensional ribbon constructed of {V6O18}6- clusters linked by a binuclear subunit of edge sharing {Cu(bpy)O3} square pyramids. Similarly, the reaction of Cu2O, Na3VO4, 2,2′:6′,2″-terpyridine, selenous acid, and water, in a mole ratio 1.52:1.00:2.02:9.31:2130 at 200°C for 67.5 h yielded β-[Cu(tpy)V2O6] (2). The structure of 2 is comprised of an undulating chain of corner sharing vanadium oxide tetrahedra, with {Cu(tpy)}2+ subunits spanning the adjacent crests and troughs.
