Synthesis, characterization and biological activity of organotitanium substituted heteropolytungstates
Abstract
Eight new compounds α- and β-MxHy[(CpTi)3XW9O37]·nH2O (M = K+, x = 4, y = 3; M = NBu4+, x = 7, y = 0; X = Si, Ge) have been synthesized from vacant heteropolytungstate precursors α-, β-[XW9O34]10− (X = Si, Ge) and Cp2TiCl2. The products were characterized by
