M_r = 1252.6, triclinic, P1, α = 11.312 (5), b = 13.147 (3), c = 25.016 (21) Å, α = 93.13 (4), β = 103.24 (4), γ = 86.28 (2)° , U = 3597.5 ų, Z = 2, μ = 0.080mm^-1, D_m = 1.116, D_x = 1.119 Mg m^-3. The final R value is 0.078 for 3329 independent reflexions. By assuming an average spherical shape for the tri-o-thymotide (TOT) molecules, the crystal structure can be visualized as a distorted non-closest hexagonal packing of spheres characterized by a periodic stacking of A and B layers. Each TOT molecule is surrounded by eight nearest neighbours. The benzene molecules are periodically distributed in three structurally different types of channels.
