“…Application of primary amines leads to tetrameric salts with a core bound by a 'cubane-like' hydrogen bonding net [26]. Secondary amines give derivatives with discrete dimeric units in the solid state [27][28][29]. So we have finite, 'point type' or zero-dimensional hydrogen bonds that cannot create crystal-wide web in both cases.…”

New salts of thiophenol with three flexible aliphatic diamines H 2 N(CH 2 ) n NH 2 (n = 2, 4 and 6) have been synthesized and characterized by elemental analyses, IR spectroscopy and X-ray crystallography in order to analyze their supramolecular architecture. Structural analyses indicate that in the crystals, proton transfer has occurred, with the -SH group giving (?) N-HÁÁÁS (-) hydrogen bonding interaction. The structure of compound 1 exhibits a two-dimensional network and compounds 2-3 a three-dimensional supramolecular networks, and each of them is based on hydrogen bonds and CHÁÁÁp interactions. The transfer of proton from the thiol to the diamines was confirmed by the solid-state FTIR spectra of 1-3.

2,2,6,6-Tetramethylpiperidinium triisopropoxysilanethiolate

Abstract: The crystal of the title compound, C9H20N+·C9H21O3SSi−, is built of aggregates, each made up of two 2,2,6,6-tetramethylpiperidinium cations and two triisopropoxysilanethiolate anions. The aggregates are linked by four N—H⋯S bonds and correspond to an R 2 4(8) graph-set motif.
