Crystal Structure of Equimolar Complex of Lauric Acid and Nicotinamide

Abstract

The title compound, C₁₂H₂₄O₂·C₆H₆N₂O, crystallized in the triclinic space group P1, with cell parameters a = 5.4694(7)Å, b = 34.636(7)Å, c = 5.045(1)Å, α = 91.94(2)°, β = 92.19(2)°, γ = 90.48(1)Å and Z = 2. The nitrogen atom of the pyridine ring of the nicotinamide hydrogen-bonds to the hydroxy group of the lauric acid. The complexes form dimers through hydrogen bonds between the amide groups. The dimers are laterally packed to form a bilayer. The bilayers are stacked to form a lamellar structure. The hydrocarbon chain has an all-trans conformation.
