The [Si(S₂O₇)₃]²⁻ Anion: A First Example of Octahedral Silicon Coordination by Three Chelating Inorganic Ligands

Abstract

The power of silicon! The unique [Si(S2O7)3]2− anion is the first example of a tetravalent silicon atom coordinated by three chelating inorganic ligands (see graphic). It forms when SiCl4 reacts with oleum at elevated temperatures and has been crystallized as its sodium and cesium salts.
