Solid State Structures of Some Dithionoamido-18-Crown-6 Ligands

Abstract

The structures of three Dithionoamido-18-crown-6 ligands have been determined by X-ray diffraction studies. The results show that the carbon and oxygen atoms on the macroring opposite the pyridine ring are disordered. A serious conformation change is noted when methyl substituents are bonded to the amide nitrogen atoms. The structures were determined by X-ray diffraction studies. The discussion of the experimental procedures used in these studies and tables of structure determination summaries, atomic parameters, and torsion angles are included in the supplementary material. The molecule contained a 2- fold axis. The unit cells of both contain two chemically similar but crystallographically distinct molecules.
