Abstract
A conventional Dawson structure polyoxomolybdovanadate cluster anion based on VVO4 tetrahedra, [Mo18O54(VO4)2]6− (1a), has been isolated from an acidified aqueous solution with the presence of triethanolamine (TEA) in the condition of heated refluence, and was characterized by single-crystal X-ray structure analysis, XRD, IR, and TG. The 51V NMR spectrum indicates that the two V atoms in 1a have the same coordination environments. The electrochemical behaviors of this compound have been investigated.
