Directing the Linkage of Small Polyoxometalate Building Blocks Using (Benzene)ruthenium Cations.

ABSTRACT: Oligomerization of monomeric molybdate and tungstate oxyanions in the presence of organometallic cations produces a group of organometallic-polyoxometalate clusters, which have diverse structures based on cubane-like {M₄O₄} units resembling the structure of oxide surfaces. This work investigated the oligomerization of [MoO₄]^2- and [WO₄]^2- oxyanions in aqueous solutions in the presence of {Ru(C₆H₆)}²⁺ as the organometallic structure-directing agents. The reactions produced a mixture of several species, and fractional crystallization by adjusting crystallization temperature and molar ratios of Ru:Mo or Ru:W allowed the isolation of seven types of (benzene)ruthenium-polyoxometalate complexes: [{
