The structure of the title solvate, C9H6O6·C2H6OS, was determined 30 years ago [Herbstein, Kapon & Wasserman (1978). Acta Cryst. B34, 1613-1617], with data collected at room temperature, and refined in the space group P21. The present redetermination, based on high-resolution diffraction data, shows that the actual space group is more likely to be P21/m. The crystal structure contains layers of trimesic acid molecules lying on mirror planes. A mirror plane also passes through the S and O atoms of the solvent molecule. The molecules in each layer are interconnected through strong O-HO hydrogen bonds, forming a two-dimensional supramolecular network within each layer. The donor groups are the hydroxyls of the trimesic acid molecules, while the acceptors are the carbonyl or the sulfoxide O atoms.
For the first report on the title solvate structure, see: Herbstein et al. (1978). For the use of trimesic acid as a building block for supramolecular networks, see: Almeida Paz & Klinowski (2004). For a description of hydrogen bonds, see: Desiraju & Steiner (1999).
