The first organically templated vanadium tellurites, [H{sub 2}en][(VO{sub 2})(TeO{sub 3})]{sub 2}.H{sub 2}O (1, en=ethylenediamine) and [H{sub 2}pip][(VO{sub 2})(TeO{sub 3})]{sub 2} (2, pip=piperazine) have been synthesized by hydrothermal reactions and structurally characterized. Both compounds feature a [(VO{sub 2})(TeO{sub 3})]{sup -} anionic layer containing V{sub 2}Te{sub 2} four-member rings and V{sub 4}Te{sub 4} eight member rings. The vanadium (V) atom is five coordinated by three tellurite oxygens and two terminal oxygen atoms in a distorted trigonal bipyramidal geometry. The interconnection of the VO{sub 5} polyhedra by bridging tellurite groups leads to a 2D corrugated anionic inorganic layer. The doubly protonated template cations and the lattice water molecules in 1 are located at the interlayer space and are involved in hydrogen bonding. The doubly protonated template cation in 2 is not involved in hydrogen bonding with the anionic inorganic layer.
