Novel examples of hybrid organic-inorganic solids based on V4O124- building blocks

New hybrid organic/inorganic copper oxovanadium [Cu(dpa)2]4V4O12, Cu2(bipy)2V4O12, Cu2(bipy)2V6O17 were obtained by soft hydrothermal routes. The first two structures present isolated [V4O12]4− anionic units, the third one exhibits the same [V4O12]4− cycles coupled by V2O5 dimeric bridges propagated as an infinite. In all the compounds described herein, the vanadium ions are as V(V), occupying solely tetrahedral sites.
