The title mol-ecule, C(17)H(20)N(2)O, is a functionalized hydrazine with benzoyl and adamantyl substituents attached to the two hydrazine N atoms. In the crystal, mol-ecules are linked via N-H⋯N hydrogen bonds, forming chains propagating along the a-axis direction. There are also C-H⋯O, C-H⋯N and C-H⋯π inter-actions present within the chains.

The asymmetric unit of the title compound, C(7)H(6)ClN(3)S, consists of two crystallographically independent mol-ecules (A and B). The dihedral angle between the benzothia-zole ring system and the hydrazine group is 8.71 (6)° in mol-ecule A and 7.16 (6)° in mol-ecule B. The N-N-C-N and N-N-C-S torsion angles involving the hydrazine group are 170.89 (9) and -9.96 (13)°, respectively, in mol-ecule A and 172.50 (9) and -7.43 (13)°, respectively, in mol-ecule B. In the crystal, neighbouring mol-ecules are connected via pairs of N-H⋯N hydrogen bonds, generating R(2) (2)(8) ring motifs, and are connected further by N-H⋯N hydrogen bonds into sheets lying parallel to the ab plane. The crystal studied was an inversion twin, the refined ratio of the twin components being 0.50 (3):0.50 (3).

The title compound, C(17)H(19)N(3)O(3)S, crystallizes with two closely similar independent mol-ecules related by a pseudotranslation of c/2. Each mol-ecule consists of three approximately planar moieties centred on the N(2)CS group and the two ring systems. The packing involves classical H bonds of the form N(amide)-H⋯S and N(hydrazine)-H⋯OC, together with various weak hydrogen bonds and N(hydrazine)-H⋯π inter-actions. The overall packing is three-dimensional, but layer substructures parallel to the xz plane can be readily identified. Each mol-ecule forms a topologically equivalent set of hydrogen-bond inter-actions.

The title compound, C(13)H(9)N(5)O(6), contains three nitro groups. It is prepared by the reaction of benzaldehyde 2,4-dinitro-phenyl-hydrazone with nitric oxide at ambient temperature. The imine group is nearly coplanar with the (2,4-dinitro-phen-yl)-hydrazine unit. The second benzene ring and the third nitro group are twisted away from this plane, with dihedral angles of 48.5 (3) and 15.2 (3)°, respectively. Weak intra-molecular N-H⋯O inter-actions are observed.

Crystals of the title compound, C(15)H(15)N(3)O(3), were obtained from a condensation reaction of 4-nitro-phenyl-hydrazine and 3-methoxy-acetophenone. In the crystal structure, the methoxy-phenyl ring is twisted slightly with respect to the nitro-phenyl-hydrazine plane, making a dihedral angle of 14.81 (8)°. The nitro and meth-oxy groups are each coplanar with the attached benzene rings. The nitro-phenyl and methoxy-phenyl groups are located on opposite sides of the C=N double bond, indicating an E configuration of the mol-ecule. Adjacent mol-ecules are linked together via N-H⋯O hydrogen bonding, forming chains along the [101] direction.
