4-Amino-N-(4,6-di­methyl­pyrimidin-2-yl)benzene­sulfonamide–1,4-di­aza­bicyclo­[2.2.2]octane (2/1)

The asymmetric unit of the title co-crystal, C₁₂H₁₄N₄O₂S·0.5C₆H₁₂N₂, comprises the sulfonamide mol­ecule and half a mol­ecule of 1,4-di­aza­bicyclo­[2.2.2]octane (DABCO), the latter being disposed about a crystallographic twofold rotation axis. In the sulfonamide mol­ecule, the aromatic rings are almost perpendicular to one another [dihedral angle = 75.01 (8)°]. In the crystal, mol­ecules are connected into a three-mol­ecule aggregate via amide–DABCO N—H...N hydrogen bonds, and these are connected into a three-dimensional architecture via amino–DABCO N—H...O and amino-pyrimidine N—H...N hydrogen bonds.
