Abstract
AbstractThe complexes of 2-(menthoxycarbonyl)ethyltin chloride, MenOCOCH2CH2SnCl3⋅L (Men = Menthyl, L = benzyl phenyl sulfoxide (bpSO), 1; 2,2’-bipyridine (bpy), 2; 1,10-phenanthroline (phen), 3) and [MenOCOCH2CH2SnCl2(OCH3)]2 (4), have been synthesized and characterized by means of elemental analysis, FT-IR, NMR (1H, 13C and 119Sn) spectra. The crystal structures of 1, 3 and 4 have been determined by single crystal X-ray diffraction. The tin atoms in 1-4 are all hexa-coordinated. The tin atom in 1 adopts a distorted [CSnCl3O2] octahedral geometry with an oxygen atom of the ligand and an intramolecular coordination of the oxygen atom from the carbonyl group to the tin atom. Complex 3 possesses a distorted [CSnCl3N2] octahedral geometry with two nitrogen atoms of a chelating phen ligand. The carbonyl oxygen atom of the ester moiety is not coordinating. Compound 4 is a centrosymmetric dimer with a four-membered Sn2O2 ring, and the tin atom has a distorted [CSnCl2O3] octahedral geometry with an intramolecular C=O→Sn coordination and intermolecular methoxy bridging.
