摘要：

Two new vanadium tellurites, Cu(TATP)V2TeO8 (1) and Cu(DPPZ)V2Te2O10 (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 [V2TeO8](n) double-chain-like ribbons linked by [Cu(TATP)(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 (V4Te4O8)(m) and (Te2O2)(n), with same handedness. Two types of helical chains are linked by mu(3)(O6) atoms to generate a V/Te/O inorganic anionic layer. The [Cu(DppZ)](2+) cationic complex fragments are covalently bonded to the layer, projecting below and above the vanadium tellurites layer. Crown Copyright (C) 2009 Published by Elsevier Inc.
