Etude spectroscopique de derives mercuriques d'amides-thiols: Partie III. Spectres de vibration et structure de complexes mercuriques des thiol-2N-méthylacétamide, thiol-3N-méthylpropanamide et N-thiol-2 éthyle)acétamide

Abstract Raman and IR spectra of (CH 3 NHCOCH 2 S) 2 Hg, (CH 3 CONHCH 2 CH 2 S) 2 Hg and CH 3 NHCOCH 2 CH 2 SHgCl have been recorded between 3800 and 60 cm −1 . Mercury is covalently bonded to two sulphur atoms in the first two compounds and to one sulphur atom and one chlorine atom in the third compound. (CH 3 NHCOCH 2 S) 2 Hg forms a tenatom ring by intramolecular hydrogen bonding NH⋯OC. In the two other complexes, weak interactions Hg⋯O are consistent with experimental results.
