In the title compound, C15H15N5O2S2, the phenyl rings make dihedral angles of 4.03 (4) and 9.77 (5)° with the plane defined by the central N—N—C—N—N atoms (r.m.s. deviation = 0.010 Å). The C—S—C—C torsion angles of the methylsulfanyl groups with their respective phenyl rings are −7.47 (13) and −72.07 (13)°. The shortest centroid–centroid distance of 3.707 Å occurs between the two π-systems N—N—C—N—N and the benzene ring in the diazene 1-position. The H atom bound to the N atom is involved in intramolecular N—H
N and N—HS contacts, while the nitro O atoms are involved in intermolecular C—HO contacts.

In the title compound, C15H15N5O2, the nitro O atoms are disordered over two sets of sites with an occupancy ratio of 0.75 (4):0.25 (4). Amine–imine tautomerism is observed in the formazan group. This was evident from the similar C—N bond distances in the formazan [1.319 (2) and 1.332 (3) Å], as well as the distribution of the imine proton in the Fourier difference map which refined to a 0.53 (3):0.47 (3) ratio. C—HO and π–π interactions [centroid–centroid distances = 3.4813 (1) and 3.3976 (1) Å] are observed in the crystal packing.

The title compound, [Co(C17H13N2O2)2(C2H5OH)2], is a CoII complex with two 4-benzoyl-3-methyl-1-phenyl-1H-pyrazol-5-olate (BMPP) ligands and two coordinating ethanol molecules. In the asymmetric unit, there are two half molecules, with the CoII atoms located on inversion centres. The two cobalt complexes have slightly different geometries and in one, the ethyl group of the ethanol is disordered over two sets of sites [occupancy ratio 0.757 (7):0.243 (7)]. Each BMPP ligand is deprotonated with the negative charge delocalized. The hydroxy group of each ethanol molecule forms hydrogen bonds with a pyrazole N atom in an adjacent BMPP ligand. Weaker C—HO and C—HN interactions link the molecules into a three-dimensional structure.

The title compound, C23H20N4O, is a heterocyclic phenylhydrazone Schiff base with a pyrazole moiety. In the crystal, a variety of interactions occur, including N—Hπ and π–π stacking between the phenyl ring of the phenylhydrazinyl group and its symmetry-generated equivalent [centroid–centroid distance = 3.6512 (7) Å].

In the title compound, [Cd(C9H10NS2)2(C5H9NO)], the CdII atom is five-coordinated in a distorted square-pyramidal geometry by four S atoms from two chelating N-ethyl-N-phenyl dithiocarbamate ligands and one N atom from a 2-ethyl-2-oxazoline ligand. Intermolecular C—Hπ interactions are observed in the crystal structure.

The title Schiff base compound, C14H14N2O3S, is non-planar, with a dihedral angle of 24.16 (7)° between the benzene rings. In the crystal, N—HO and N—HN hydrogen bonds link the molecules into a layer parallel to (011). Intra- and interlayer C—HO interactions and π–π interactions [centroid–centroid distances = 3.8900 (9) and 3.9355 (8) Å] are also present.

In the title compound, C23H18N6O5·C2H6O, all three benzene rings lie in an approximate plane [maximum deviation = 0.2688 (16) Å] that makes an angle of 53.56 (3)° with the plane of the pyrazolone ring. Intramolecular N—HO hydrogen bonds occur. In the crystal, the ethanol solvent molecule links adjacent molecules through N—HO—HO hydrogen bonds, leading to an infinite chain along the c-axis direction. The ethyl group of the ethanol solvent molecule is disordered over two set of sites in a 0.762 (5):0.238 (5) ratio.
