The title molecule, C18H21Cl2NO3S2, contains one chiral carbon center and the absolute sterochemistry has been confirmed as as R. An intramolecular N—H
O hydrogen bond occurs and the dihedral angle between the benzene rings is 64.5 (1)°. In the crystal, the molecules are linked by weak C—HO hydrogen bonds, forming a zigzag chain structure extending along the c-axis direction.

In the title compound, [Fe(C5H5)(C9H6ClN2)], the two cyclopentadienyl rings are almost parallel, subtending a dihedral angle of 3.01 (5)°. The dihedral angle between the substituted cyclopentadienyl ring and the pyrimidinyl ring is 12.02 (1)°. The conformation of the two cyclopentadienyl rings in the ferrocenyl moiety is eclipsed.

In the title compound, C30H25N3O3, the central imidazole ring forms dihedral angles of 77.34 (6), 12.56 (6) and 87.04 (6)°, respectively, with the o-nitrobenzene ring and the phenyl substituents in the 5- and 4-positions. The molecular conformation is stabilized by weak intramolecular C—Hπ interactions. In the crystal, molecules are linked by O—HN hydrogen bonds, forming chains running parallel to the b-axis direction.

In the title molecule, C14H18ClN5O2S, the six atoms of the 1,6-dihydropyridazine ring are essentially coplanar (r.m.s. deviation = 0.008 Å), and the dihedral angle between this and the 1,3,4-thiadiazole ring is 62.06 (10)°. In the crystal, centrosymmetrically related molecules are linked by intermolecular C-H-O hydrogen bonding to form a supramolecular dimer. The terminal ethyl group is statistically disordered over two positions.
