Solid-state reactions of AgAc with TabHPF6 at room temperature -: Isolation and structural characterisation of an unusual octadecanuclear silver thiolate cluster [Ag9(Tab)8(MeCN)8]2(PF6)18•4MeCN [Tab=4-(trimethylammonio)benzenethiolate]

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)(PF6)(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 saddleshaped Ag6S6 fragment and two identical Ag5S6 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)(PF6)(18) and might have the Ag18S16 core structure of 1 based on elemental analysis, IR spectroscopy, H-1 NMR spectroscopy, luminescence spectra, XRD and TGA measurements.
