A methyl-coordinated Rh^III ion in methyl­penta­amminerhodium(III)–chloro­pentaammine­rhodium(III)–di­thionate (0.73/2.27/3)

Some disorder is seen in the crystal structure of [Rh(CH₃)(NH₃)₅]_0.73[RhCl(NH₃)₅]_2.27(S₂O₆)₃. It is, however, clear that the methyl group has a pronounced trans influence on the Rh—N distance, with an elongation of 0.11 Å. No trans influence is observed for the Rh—N distance due to the Cl⁻ ion. Both observations are in agreement with observations in equivalent cobalt complexes.
