Abstract
In the title co-crystal, C16H14N4O2·2C7H6O2, the 3,4-bis[(pyridin-3-ylmethyl)amino]cyclobut-3-ene-1,2-dione squareamide molecules assemble into chains along the b axis via N—H⋯O hydrogen bonds. The benzoic acid molecules then hydrogen bond to the pyridine rings via O—H⋯N hydrogen bonds, supported by weaker C—H⋯O hydrogen bonds, forming extended ribbons. The asymmetric unit consists of a half squareamide molecule, sitting on a special position around a twofold axis, and one benzoic acid molecule on a general position.
