Abstract
The room‐temperature solid‐state reaction of silver acetate with TabHPF~6~ [Tab = 4‐(trimethylammonio)benzenethiolate] followed by recrystallization from MeCN afforded a unique octadecanuclear silver thiolate complex [Ag~9~(Tab)~8~(MeCN)~8~]~2~(PF~6~)~18~·4MeCN (1). An X‐ray analysis of 1 revealed that the structure of [Ag~9~(Tab)~8~(MeCN)~8~]~2~^18+^ contains an unprecedented tubular motif in which one central saddle‐shaped Ag~6~S~6~ fragment and two identical Ag~5~S~6~ fragments are interconnected by a pair of Ag atoms and four Ag−S bonds. The solid‐state product was assumed to be [Ag~9~(Tab)~8~]~2~(PF~6~)~18~ and might have the Ag~18~S~16~ core structure of 1 based on elemental analysis, IR spectroscopy, ^1^H NMR spectroscopy, luminescence spectra, XRD and TGA measurements.
