The importance of Au⋯π(aryl) interactions in the formation of spherical aggregates in binuclear phosphane gold(<scp>i</scp>) complexes of a bipodal thiocarbamate dianion: a combined crystallographic and computational study, and anti-microbial activity

Abstract

Compact molecular structures of antimicrobial (R₃PAu)₂L (R = Et (<bold>1</bold>), Ph ((<bold>2</bold>) and Cy ((<bold>3</bold>); LH₂= {1,4-[MeOC(S)-N(H)]₂C₆H₄}), arise from intramolecular Au⋯π(aryl) interactions, proven by theory to be attractive and 12 kcal mol^–1more stable than anticipated Au⋯O interactions.
