4-Amino-N-(4,6-di-methyl-pyrimidin-2-yl)benzene-sulfonamide-1,4-di-aza-bicyclo-[2.2.2]octane (2/1).


ABSTRACT: The asymmetric unit of the title co-crystal, C12H14N4O2S·0.5C6H12N2, comprises the sulfonamide mol-ecule and half a mol-ecule of 1,4-di-aza-bicyclo-[2.2.2]octane (DABCO), the latter being disposed about a crystallographic twofold rotation axis. In the sulfonamide mol-ecule, the aromatic rings are almost perpendicular to one another [dihedral angle = 75.01?(8)°]. In the crystal, mol-ecules are connected into a three-mol-ecule 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.
