Polyoxomolybdate(VI) anion stabilized by ammonium cation via CS₂ elimination from N-benzyl-N-methylferrocenyl dithiocarbamate

Abstract

A new polyoxomolybdate [(FcCH₂)NH₂(CH₂C₆H₅)]₄[Mo₈O₂₆] has been obtained by the reaction of ammonium molybdate and potassium N-benzyl-N-methylferrocenyl dithiocarbamate in mild acidic condition. The resulting cluster has been characterized by microanalyses, electronic absorption, photoluminescence, IR, and ¹H NMR spectroscopy, and its electrochemical properties. Quantum chemical calculations have been performed in order to explain the CS₂ elimination from the dithiocarbamate moiety. Single-crystal X-ray analysis of this compound reveals that the ammonium cation generates an intricate 2-D supramolecular architecture.
