ABSTRACT
In the title 11 cocrystal, C(10)H(8)N(2)S(2)·C(8)H(6)O(4), the asymmetric unit contains an isophthalic acid mol-ecule and a 4,4'-dipyridyl disulfide mol-ecule. The two carboxyl groups of isophthalic acid inter-act with neighbouring 4,4'-dipyridyl disulfide mol-ecules through O-Hâ¯N hydrogen bonds, forming a one-dimensional zigzag chain. Neighbouring chains are linked to each other via π-π stacking inter-actions between the pyridyl rings of adjacent 4,4'-dipyridyl disulfide mol-ecules [centroid-centroid distance = 3.7346â
(6)â
Å], resulting in a layered motif. The dihedral angle between pyridine rings of 84.13â
(7)° and the C-S-S-C torsion angle of 91.95â
(1)° confirm the gauche conformation of 4,4'-dipyridyl disulfide.
