In the title compound, C15H12ClNO2S, the indole ring is essentially planar (r.m.s. deviation = 0.0107 Å) and makes a dihedral angle of 85.01 (6)° with the benzene ring. In the crystal, three C—HO hydrogen bonds result in a hydrogen-bonded spiral running parallel to the c axis.

In the title compound, C18H18N4O4S2, the mean planes passing through the tosyl benzene rings form dihedral angles of 48.42 (9) and 15.1 (1)° with the aminopyrimidine ring. In the crystal, molecules associate via N—HN and N—HO hydrogen bonds, forming extended hydrogen-bonded sheets that lie parallel to the bc plane. The N—HN hydrogen bonds propagate along the b-axis direction, while the N—HO hydrogen bonds propagate along the c-axis direction.

In the title compound, C14H12N4, the dihedral angle between the indole ring system (r.m.s. deviation = 0.010 Å) and the imidazole ring is 77.70 (6)°. In the crystal, molecules are linked by C—HN hydrogen bonds. One set of hydrogen bonds forms an undulating chain running parallel to the b-axis direction, while the other undulating chain is parallel to the c-axis direction. In combination, (100) sheets result.
