Self-assembly of a 3-D self-catenated framework based on [V_4O_(12)]~4~~ polyoxoanions and cobalt-organic polymer

摘要

Reaction of a flexible ligand with cobalt salt in the presence of polyoxovanadate produces a new composite solid, CO_2(btx)_4V_4O_(12), 1 (btx=l,4-bis(triazol-l-ylmethyl)benzene). The structure of 1 was determined by single-crystal X-ray diffraction analysis and further characterized by elemental analysis, IR spectrum, and TG analysis. Compound 1 exhibits a 3-D 4,6-connccted self-catenated net constructed from [V_4O_(12)]~(-4) building blocks and the {Co(btx)_2}~(2+) 3-D metal-organic cation polymer. The electronic properties of 1 have been investigated.
