[(ⁱPrSn)₁₂O₁₄(OH)₆][(ⁱPrSn)₃(OV)₄O₁₀(OH)₃] · 4DMSO: Evidence for the Formation of Contact Ion Pairs Resulting from the Nucleophilic Attack on a Square Pyramidally Coordinated Tin Atom

Abstract

The title compound has been prepared via self-assembly of an RSn and VO source. In the solid, the cation and anion form an intimate ion pair via a V˭O−Sn bond expanding the coordination sphere at tin from square-pyramidal to trigonal-prismatic.
