Abstract

The tridentate title ligand was found to act as an (N_eqN _axO_eq) = (N_amide,N_imine,O _phenolate) ligand as well as an (N_axN_eqO _ax) ligand in pentacoordinate silicon complexes depending on the substituents at the Si atom. Its two notably different coordination modes in (N_eqN_axO_eq)Si(CH₂)₃ and (N_aXN_eqO_ax)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.
