In the title compound, C30H27ClN4O, the central pyrrolidine ring adopts an envelope conformation with the methylene C atom being the flap. The quinoxaline and indane rings are each essentially planar, with r.m.s. deviations of 0.027 (1) and 0.0417 (1) Å, respectively. The pyrrolidine ring forms dihedral angles of 88.25 (1) and 83.76 (1)° with the quinoxaline and indane rings, respectively. A weak intramolecular C—HN interaction is observed. In the crystal, C—Hπ interactions lead to supramolecular chains along [101] that assemble in the ac plane. Connections along the b axis are of the type ClCl [3.6538 (16) Å].

In the title 2-[(4,6-diaminopyrimidin-2-yl)sulfanyl]acetamides, both compounds have a folded conformation about the methylene C atom of the thioacetamide bridge, with the pyrimidine ring being inclined to the benzene ring by 56.18 (6) and 67.84 (6)°. In both molecules, there is an intramolecular N—HN hydrogen bond stabilizing the folded conformation.

In the title compound, C14H10ClNO2, obtained by the condensation of 4-chloroaniline and piperonal, the five-membered ring is almost planar (r.m.s. deviation = 0.023 Å) and the dihedral angle between the aromatic rings is 43.22 (14)°. In the crystal, a short OCl contact of 3.173 (2) Å is observed. The molecules are arranged into corrugated (010) layers.

The cation and anion in N,N,N-triethylhydroxylammonium chloride are linked by an O—HCl hydrogen bond. The extended structure displays C—HCl and C—HO hydrogen bonds, resulting in layers lying parallel to the (100) plane: further C—HCl contacts connect the sheets into a three-dimensional network.

In the title compound, the benzene rings make a dihedral angle of 62.73 (9)° with each other. In the crystal, molecules are linked by a pair of C—Clπ interactions, forming an inversion dimer. A short HL·HL contact links the dimers, forming a ribbon propagating along the c-axis.

The molecule of the title compound, C8H6ClN3O2, is built up from fused five- and six-membered rings connected to a chlorine atom and to nitro and methyl groups. The indazole system is essentially planar with the largest deviation from the mean plane being 0.007 (2) Å. No classical hydrogen bonds are observed in the structure. Two molecules form a dimer organised by a symmetry centre via a close contact between a nitro-O atom and the chlorine atom [at 3.066 (2) Å this is shorter than the sum of their van der Waals radii].
