Electrocatalytic oxidation and detection of hydrazine at carbon nanotube-supported palladium nanoparticles in strong acidic solution conditions

The asymmetric unit of the title compound, C9H14OS4, comprises two crystallographically independent mol­ecules with similar conformations. In each mol­ecule, an intra­molecular C—H⋯O hydrogen bond generates a six-membered ring, producing an S(6) ring motif. All of the six-membered dithia­cyclo­hexane rings adopt chair conformations. The crystal structure is stabilized by four inter­molecular C—H⋯O and one C—H⋯S inter­action.

2-(1,3-Dithian-2-yl)-1,3-dithiane-2-carbaldehyde.

In the mol­ecule of the title compound, C10H12N2, the six- and five-membered rings are almost co-planar, forming a dihedral angle of 3.56 (8)°. In the crystal structure, neighbouring mol­ecules are linked together by inter­molecular N—H⋯N hydrogen bonds into one-dimensional infinite chains along the c axis. The crystal structure, is further stabilized by weak inter­molecular C—H⋯π and π–π stacking [centroid–centroid distance = 3.8892 (9) A] inter­actions.

2-p-Tolyl-4,5-dihydro-1H-imidazole.

The title Schiff base compound, C23H30N2O2, has crystallographic twofold rotation symmetry. An intra­molecular O—H⋯N hydrogen bond forms a six-membered ring, producing an S(6) ring motif. The imino group is coplanar with the benzene ring. The two benzene rings are almost perpendicular to each other, making a dihedral angle of 87.38 (4)°. In the crystal structure, neighbouring mol­ecules are linked along the c axis by weak inter­molecular C—H⋯O hydrogen bonds and are further packed into columns along the b axis, forming sheets which are parallel to the bc plane.

4,4',5,5'-Tetra-methyl-2,2'-[1,1'-(propane-1,3-diyldinitrilo)diethyl-idyne]diphenol.

The title Schiff base compound, C15H14N2O2, consists of two crystallographically independent mol­ecules, A and B. Mol­ecule A is almost planar, whereas mol­ecule B is slightly twisted, the dihedral angles between the benzimidazole group and the benzene rings being 2.65 (12) and 13.17 (15)°, respectively. The methyl group of mol­ecule B is disordered over two positions, with a refined site-occupancy ratio of 0.581 (7):0.419 (7). In each mol­ecule, intra­molecular O—H⋯N hydrogen bonds generate S(6) ring motifs. In the crystal structure, both types of mol­ecules are linked via inter­molecular bifurcated N—H⋯O hydrogen bonds into one-dimensional extended chains along [010] and form R12(5) ring motifs. The crystal structure is further stabilized by inter­molecular C—H⋯π and π–π inter­actions [centroid–centroid distances = 3.4758 (16)–3.596 (2) A].
