4-Amino-N-(2,3-di­hydro-1,3-thia­zol-2-yl­idene)benzene­sulfonamide–2,4,6-tris­(pyr­idin-2-yl)-1,3,5-triazine (1/1)

The sulfa­thia­zole mol­ecule in the title 1:1 co-crystal, C(9)H(9)N(3)O(2)S(2)·C(18)H(12)N(6), adopts an approximate L-shape [dihedral angle between the five- and six-membered rings = 86.20 (9)°] and features an intra­molecular hypervalent S⋯O inter­action [2.8666 (15) Å]. Overall, the triazine mol­ecule has the shape of a disk as the pendant pyridine rings are relatively close to coplanar with the central ring [dihedral angles = 18.35 (9), 6.12 (9) and 4.67 (9)°]. In the crystal packing, a linear supra­molecular chain aligned along [01-1] is formed as a result of amino–pyridyl N—H⋯N hydrogen bonding with syn-disposed pyridyl mol­ecules of one triazine, and amine–pyridyl N—H⋯N hydrogen bonding with the third pydridyl ring of a second triazine mol­ecule. A three-dimensional architecture arises as the chains are connected by C—H⋯O inter­actions.
