The hydrothermal reaction of Na3VO4, H3PO4, 2,2′:6′,2″-terpyridine and water in the mole ratio 2.73: 10.1: 1.00: 1220 provided orange crystals of [VO2(terpy)][(VO2)2(PO4)] in good yield. The structure consists of {(VO2)2(PO4)}n-n layers with charge-compensating {VO2(terpy)}1+ molecular cations occupying the interlamellar regions. The layer structure consists of a network constructed from chains of corner-sharing {VO5} square pyramids, linked through {PO4}3- tetrahedra. The layer is characterized by cyclic eight polyhedra connects producing sixteen member rings {V6P2O8} which fuse to produce the two-dimensional connectivity. Crystal data: C15H11N3O10PV3, monoclinic, C2/c, a = 12.315(1), b = 10.835(1), c = 29.181(3) Å, β = 101.618(2)°, V = 3814.2(6) Å3, Z = 8, Dcalc = 2.010 g cm-3.
