Synthesis, structure and characterization of two organic–inorganic hybrid ruthenium-containing polyoxometalates

Abstract

Two isostructural organic-inorganic hybrid ruthenium-containing polyoxometalates (POMs), NaH₅[(P₂M₁₈O₆₂)]·(Ru(dmso)₄Cl₂)₄·nH₂O (M = W, n = 12 (1); M = Mo, n = 10 (2)), have been synthesized and characterized by single-crystal X-ray diffraction, IR spectroscopy, thermogravimetric (TG) analyses, and elemental analyses. Single-crystal X-ray diffraction analyses indicate that they are co-crystals and that the two polyoxoanions are structurally similar aside from the identity of the metal ions present. Furthermore, the electrochemical behavior of the POMs was investigated in aqueous solution to establish the redox properties associated with having W versus Mo in the structures.
