Crown thioether complexes of p-block elements: crystal and molecular structures of SbCl3·9s3 (9s3 = 1,4,7-trithiacyclononane) and 2SbCl3·18S6 (18S6 = 1,4,7,10,13,16-hexathiacyclooctadecane)

Abstract

The first crown thioether complexes of Sb^III and Bi^III, as representative p-block elements, have been isolated, viz SbCl₃·9S31, BiCl₃·9S3·0.5 MeCN, SbCl₃·15S5, 2SbCl₃·18S6 2 and BiCl₃·18S6; X-ray crystal structure determinations of 1 and 2 establish full participation of ligand S-donor sites in metal ⋯ sulphur bonding in each case.
