1,1'-Binaphthyl-2,2'-dicarboxylic acid (1) forms crystalline inclusion compounds with 1-PrOH (2:1) and t-BuOH (1:1). X-ray crystal structures of the two inclusion compounds are reported. Crystals of 1·1-PrOH (2: 1) show triclinic ( {Mathematical expression}) symmetry with the unit cell dimensions a = 10.160(1), b = 14.050(2), c = 15.167(1) Åα = 100.37(1), β = 104.40(1), and γ =94.82(1)°. Crystals of 1s·t-BuOH (1: 1) are monoclinic (P21/n) with the cell dimensions a = 10.603(5), b = 14.377(4), c = 15.664(7) Å, β = 104.24(4)°. In both structures, H-bonded loops involving host -000H functions and guest -OH groups establish the supramolecular association. They relate these coordinatoclathrates to previous alcohol inclusions of 1. Due to the unusual 2:1 (host: guest) stoichiometry, additional dimer-like interactions between -000H groups of host molecules are found in the 1-PrOH inclusion compound. From the point of view of topology these structures can be referred to as channel inclusion compounds.
