Abstract
The structure of the p-n-heptyloxybenzoic acid–p-n-hexyloxybenzoic acid crystal, obtained in the dual system of homologues of p-n-alkyloxybenzoic acids exhibiting mesomorphic properties has been studied by X-ray diffraction analysis at a temperature of 120 K. The crystals are triclinic, sp. gr. P\(\bar {1}\), a = 4.6380(7) Å, b = 8.0158(12) Å, c= 17.673(3) Å, α = 81.019(7)°, β = 85.632(7)°, γ = 76.935(7)°, Z = 2. The molecules in the cocrystal are combined in dimers by hydrogen bonds. The probability and conditions of the formation of cocrystals of the 1 : 1 and 1 : 2 compositions in such systems are discussed.
