{N-[1-(2-Oxidophenyl)ethylidene]-dl-alaninato}(pentane-1,5-diyl)silicon(IV)

Abstract

The title SiIV complex, C16H21NO3Si, is built up by a tridentate dinegative Schiff base ligand bound to a silacyclohexane unit. The coordination geometry of the pentacoordinated SiIV atom is a distorted trigonal bipyramid. The presence of the silacyclohexane ring in the complex leads to an unusual coordination geometry of the SiIV atom with the N atom from the Schiff base ligand and an alkyl-C atom in apical positions of the trigonal bipyramid. There is a disorder of the methyl group at the imine bond with two orientations resolved for the H atoms [major orientation = 0.55 (3)]. In the crystal, C—H...O interactions are found within corrugated layers of molecules parallel to the ab plane.
