Synthesis and Characterization of Group 4 Organometal Oxide Complexes
The organometallic substituted Keggin polyoxoanions ($\eta\sp5$-C$\sb5$(CH$\sb3$)$\sb5$) MPW$\sb $O$\sb{39}$((n-C$\sb4$H$\sb9$)$\sb4$N) $\sb4$, M = Ti(1), Zr(2), or Hf(3), were prepared by reaction of ($\eta\sp5$-C$\sb5$(CH$\sb3$)$\sb5$) MCl$\sb3$ with the lacunary Keggin heteropolyanion …

Organic-inorganic hybrid materials: new functionalised polyoxotungstates
Polyoxometalates are the polyoxoanions of the early transition metals, especially tungsten, molybdenum and vanadium. Although they were first described in the 19th century, their development was slow until modern experimental techniques enabled a greater understanding of their structures and …

Characterization of a platinum-substituted keggin anion and studies of robust, hydrogen-bonded polyanion aggregates
Solution and solid-state studies of platinotungstate and platinomolybdate heteropolyanions were carried out. Salts of the Keggin-type -SiPtW11O406- anion (1) were prepared through the reaction of K8SiW11O39.13H2O with K2Pt(OH)6 and acidification of the reaction solution to pH 4 with HNO3. Infrared …
