title: 4-Amino-N-(4,6-dimethyl-pyrimidin-2-yl)benzene-sulfonamide-benzoic acid (1/1).
abstract: The constituents of the title co-crystal, C(12)H(14)N(4)O(2)S·C(7)H(6)O(2), are connected by an eight-membered hetero-synthon {⋯NCNH⋯OCOH}, whereby the carb-oxy-lic acid forms donor and acceptor hydrogen bonds with a pyrimidine N atom and the adjacent amine, respectively. The dimeric aggregates thus formed are arranged in rows with their terminal NH(2) groups forming N-H⋯O hydrogen bonds with neighbouring aggregates to form a two-dimensional array in the ac plane with an overall T-shaped topology. Layers inter-digitate along the b axis being connected by C-H⋯O, C-H⋯π and π-π [centroid-centroid distance = 3.6316 (19) Å] inter-actions.
