Abstract
The phase diagram of the phloroglucinol (1,3,5-trioxybenzol)-dimethyl sulfoxide system is studied. The system is found to form a 1:1 molecular complex of phloroglucinol with dimethyl sulfoxide. The crystal structure of the complex is determined. The crystallographic data for C8H12O4S, M = 204.24, monoclinic system, P21/n space group, unit cell parameters: a = 9.0345(2) Å, b = 9.6895(3) Å, c = 10.9960(3) Å, β = 98.865(1)°, V = 951.09(4) Å3, Z = 4, dx = 1.426 g/cm3, R1 = 0.0283, T = 150 K. The molecules are joined in a supramolecular ensemble via O-H⋯O hydrogen bonds.
