Dicyclohexyltin N-[(E)-(5-chloro-2-hydroxyphenyl) methylene]-(L)-isoleucinate

摘要

The tin atom in the title compound is in a distorted trigonal bipyramidal geometry and forms a five-and six-membered chelate rings with the tridentate ligand.The structural chemistry of organotin complexes with Schiff bases derived from alpha-amino acids continues to receive attention owing to their biological properties,especially their anti-tumour activities.The coordination geometry about the tin atom in the title compound is that of a distorted trigonal bipyramid with two cyclohexyl groups (C14 and C20) and the imino N1 atom in equatorial positions and a unidentate carboxylate group oxygen Ol and a phenoxide O3 atom in axial sites (Fig.1).The bond angle of Ol-Sn-O3 is 153.84(12) deg and the sum of trigonal angles is 359.6 deg.Distortions from the ideal geometry may be rationalized,in part,by the restricted bite angles of the tridentate ligand.
