Abstract
The hydroquinone-dimethyl sulfoxide-toluene system was investigated by thermal and X-ray diffraction analyses. The crystal structure of the 1:1 complex of hydroquinone with dimethyl sulfoxide was determined. Crystal data: C8H12O3S, M = 188.24, triclinic system, space group P1, unit cell parameters: a = 7.4202(2) Å, b = 8.4046(3) Å, c = 8.7340(3) Å; α = 100.830(1)°, β = 99.794(1)°, γ = 114.129(1)°; V = 469.35(4) Å3, Z = 2, dcalc = 1.332 g/cm3, R1 = 0.028, T = 100 K. The molecules are linked in a supramolecular assembly via D-H…A hydrogen bonds (D = O, C; A = O, π).
