Abstract
The 1:1 adduct of 4-aminobenzoic acid (PABA) with 4-aminobenzonitrile (PABN ), C7H7NO2. C7H6N2, consists of a primary centrosymmetric cyclic hydrogen-b onded PABA dimer interaction [O ... O 2.640 (3) Angstrom] peripherally link ed into chains by weaker hydrogen bonds via a head-to-tail PABN interaction [N ... N 3.179 (4) and N ... O 3.062 (4) Angstrom], and is linked between the chains by amine-N (PABN) to amine-N (PABA) interactions [N ... N 3.233 (5) Angstrom]. No proton transfer occurs.
