2‐Amino­quinolin‐8‐yl p‐toluene­sulfonate

The essentially planar quinoline fragment and the aromatic ring of the toluenexadsulfonate group of the title compound, C16H14N2O3S, form a dihedral angle of 52.2u2005(1)°; the torsion angle about the central bridge C—O—S—C is −69.3u2005(2)°. The N—H⋯N and N—H⋯O hydrogen bonds, involving the H atoms of the amino group and the quinoline and sulfonyl N and O atoms [N⋯N = 3.055u2005(3)u2005A and N⋯O = 3.058u2005(2)u2005A], link the molxadecules into dimers; a C—H⋯O interxadaction formed by the CH group in position 4 of the quinoline group [C⋯O = 3.293u2005(3)u2005A] further links the dimers into infinite chains running along the diagonal of the ab plane.

2,2-Dimethyl-5-(4H-1,2,4-triazol-4-ylamino­methyl­ene)-1,3-dioxane-4,6-dione monohydrate
