Two new vanadium tellurites, Cu(TATP)V{sub 2}TeO{sub 8}(1) and Cu(DPPZ)V{sub 2}Te{sub 2}O{sub 10}(2), (TATP=1,4,8,9-tetranitrogen-trisphene, DPPZ=dipyridophenazine) have been synthesized under hydrothermal conditions and structurally characterized by elemental analyses, IR, and single-crystal X-ray diffraction. Compound 1 features an interesting two-dimensional layer structure constructed by [V{sub 2}TeO{sub 8}]{sub n} double-chain-like ribbons linked by [Cu(TATP)]{sup 2+} bridges. Compound 2 consists of two types of chiral layers: one left-handed and the other right-handed, which lead to racemic solid-state compound. In each layer, there exist two types of inorganic helical chains (V{sub 4}Te{sub 4}O{sub 8}){sub n} and (Te{sub 2}O{sub 2}){sub n}, with same handedness. Two types of helical chains are linked by mu{sub 3}(O6) atoms to generate a V/Te/O inorganic anionic layer. The [Cu(DPPZ)]{sup 2+} cationic complex fragments are covalently bonded to the layer, projecting below and above the vanadium tellurites layer. - Graphical abstract: The changes of the size of the rigid aromatic chelate ligands may influence the structures of the V-Te-O framework.
