The tridentate title ligand was found to act as an (NeqN axOeq) = (Namide,Nimine,O phenolate) ligand as well as an (NaxNeqO ax) ligand in pentacoordinate silicon complexes depending on the substituents at the Si atom. Its two notably different coordination modes in (NeqNaxOeq)Si(CH2)3 and (NaXNeqOax)SiPhMe were studied with X-ray structure analysis as well as 29Si CP/MAS NMR spectroscopy together with quantum chemical calculations of geometry and NMR chemical shielding tensors.
