Hexacoordinate silicon bischelates with bulky monodentate alkyl ligands tend to ionize, while those with electron-withdrawing CF3 substituents on the chelate rings resist ionization. A hexacoordinate silicon complex with both of these structural features was prepared and was found, by its temperatur...
