Octa(p-ydroxy)octakis(propyloxy)calix[8]arene.9(pyridine).2(H2O) crystallises in the triclinic space group P-1, a = 14.083(2), b = 14.478(2), c = 15.652(2) Å, α = 70.109(4), β = 74.146(3), γ = 75.572(4)°, V = 2843(1) Å3, Z = 1. Refinement led to a final R1 value of 0.0757 for 4693 reflections. The calixarene sits around a crystallographic centre of inversion and is in the 'chair-like' conformation. All p-hydroxyl groups form hydrogen bonds with either pyridine or water molecules leading the extended structure to be composed of infinite ribbons parallel to the [1,0,-1] direction
