Complexes of this bulky anionic ligand often adopt with low coordination numbers. Examples include Ti(silox)3, Nb(silox)3(PMe3), and ()−. ==Properties of silox and related complexes== The sodium derivative, which has salt-like properties, is a cubane cluster.〔Lerner, Hans-Wolfram; Scholz, Stefan; Bolte, Michael "The Sodium Siloxides (tBu3SiONa)4 and (tBu2PhSiONa)4: Synthesis and X-ray Crystal Structure Analysis" Organometallics 2002, 21, 3827-3830. 〕 Related bulky anionic ligands include C5Me5−, (Me3Si)2N−, and NacNac−. Silox has a larger cone angle than C5Me5− and is a poorer donor. It is also larger than silylamides. For these reasons, silox anion forms highly unsaturated complexes. Complexes with high coordinative unsaturation display high reactivity so long as they do not undergo intramolecular reactions. Silox offers this possibility. Examples of high reactivity exhibited by metal-silox compounds include the C-O bond in carbon monoxide and the C-N bond in pyridine.〔Peter T.
