In the title compound, [Ni(C8H14N6S2)], the NiII ion is coordinated by N2S2 donor atoms of the tetradentate thiosemicarbazone ligand, and has a slightly distorted square-planar geometry. In the crystal, inversion-related molecules are linked via pairs of N—H
N and N—HS hydrogen bonds, forming R22(8) ring motifs. Molecules are further linked by slightly weaker N—HN, N—HS and C—HS hydrogen bonds, forming two-dimensional networks which lie parallel to the bc plane.

In the title compound, C24H22N2O2, the central imidazole ring makes dihedral angles of 49.45 (8), 88.94 (9) and 19.43 (8)° with the benzene ring and the two phenyl rings, respectively. The dihedral angle between the phenyl rings is 77.86 (9)°, and they form dihedral angles of 49.06 (9) and 67.31 (8)° with the benzene ring. In the crystal, molecules are linked by O—HN hydrogen bonds, forming chains along the b axis. These chains are connected by C—HO hydrogen bonds, forming a two-dimensional network parallel to (100). In addition, C—Hπ interactions are also observed. The terminal C and O atoms of the ethanol group are disordered over two sets of sites with an occupancy ratio of 0.801 (5):0.199 (5).

In the title compound, C21H24BrNO4, the dihedral angle between the heterocyclic ring and the pendant aromatic ring is 80.20 (13)°. The hexahydroquinone [i.e. the one with the C=O group] ring adopts a sofa conformation. An intramolecular O—HO hydrogen bond generates an S(6) ring motif. The ethyl group is disordered over two sets of sites with a refined site occupancy ratio of 0.633 (10):0.366 (10). In the crystal, molecules are linked by N—HO interactions, forming chains parallel to [101]. There are no significant C—Hπ or π–π interactions in the crystal structure.
