Abstract

ABSTRACT
We synthesized and characterized a new S4-based zinc complex with thione
[TtixylZnSTmxyl] 2 as sulfur-donor ligand. Structural determination by X-ray diffraction
indicated that the coordination geometry around zinc atom is close to regular
tetrahedral with S─Zn(1)─S bond angles in the range 106-113o. The reactivity
studies showed that complex 2 is much less susceptible to methylation than that of
complex [TtixylZnSC6H5] 1, which contains thiolate as sulfur-donor ligand. This
decrease in the nucleophilicity could be explained by electronic effects of thione
versus thiolate.
