Isonicotinonitrile–benzoic acid (1/1)

Abstract

In the title 1:1 adduct, C6H4N2·C7H6O2, the carboxyl group and its attached phenyl ring are essentially coplanar, being twisted from each other by a dihedral angle of only 2.05 (3)°. In the crystal, the molecules are connected via O—H...N and C—H...O hydrogen bonds, building an R22(7) ring. Molecules are further linked through π–π interactions [centroid–centroid distance of 3.8431 (8) and 3.9094 (8) Å], leading to a one-dimensional chain parallel to the b axis.
