Bottom Line: In the asymmetric unit of the title co-crystal, C(12)H(14)N(4)O(2)S·C(7)H(5)NO(4), the sulfamethazine and 2-nitro-benzoic acid mol-ecules form a heterodimer through inter-molecular amide-carb-oxy-lic acid N-H⋯O and carb-oxy-lic acid-pyrimidine O-H⋯N hydrogen-bond pairs, giving a cyclic motif [graph set R(2) (2)(8)].The dihedral angle between the two aromatic ring systems in the sulfamethazine mol-ecule is 88.96 (18)° and the nitro group of the acid is 50% rotationally disordered.Secondary aniline N-H⋯O(sulfone) hydrogen-bonding associations give a two-dimensional structure lying parallel to the ab plane.

ABSTRACT
In the asymmetric unit of the title co-crystal, C(12)H(14)N(4)O(2)S·C(7)H(5)NO(4), the sulfamethazine and 2-nitro-benzoic acid mol-ecules form a heterodimer through inter-molecular amide-carb-oxy-lic acid N-H⋯O and carb-oxy-lic acid-pyrimidine O-H⋯N hydrogen-bond pairs, giving a cyclic motif [graph set R(2) (2)(8)]. The dihedral angle between the two aromatic ring systems in the sulfamethazine mol-ecule is 88.96 (18)° and the nitro group of the acid is 50% rotationally disordered. Secondary aniline N-H⋯O(sulfone) hydrogen-bonding associations give a two-dimensional structure lying parallel to the ab plane.
