Abstract

In the asymmetric unit of the title co-crystal, C7H 5NO4·C12H14N 4O2S, there are two independent but conformationally similar heterodimers, which are formed through intermolecular N - H⋯Ocarboxy and carboxyl-pyrimidine O - H⋯N hydrogen-bond pairs, giving a cyclic motif [graph set R22(8)]. The dihedral angles between the rings in the sulfonamide molecules are 78.77 (8) and 82.33 (9)°while the dihedral angles between the ring and the CO2H group in the acids are 2.19 (9) and 7.02 (10)°. A two-dimensional structure parallel to the ab plane is generated from the heterodimer units through hydrogen-bonding associations between NH2 and sulfone groups. Between neighbouring two-dimensional arrays there are two types of aromatic π-π stacking interactions involving either one of the pyrimidine rings and a 4-nitrobenzoic acid molecule [minimum ring centroid separation = 3.5886 (9) Å] or two acid molecules [minimum ring centroid separation = 3.7236 (10) Å].
