4-Carboxybenzylidene-4′-hexylaniline (1) exhibits enantiotropic smectic F, smectic C, and nematic phases. It crystallizes in the space group P1 (#2) with cell parameters a = 6.4250(18)Å, b = 8.495(2)Å, c = 16.665(5)Å, α = 93.09(2)°, β = 98.399(17)°, γ = 110.373(14)°, Z = 2, and 838.2(4)Å3. The molecule contains intermolecular hydrogen bonds, resulting in centrosymmetric dimers. The two benzene rings are nearly coplanar. The molecules form a tilted layer structure via intermolecular O-H…O, C-H…O, C-H…π and π…π interactions.
