In the title compound, C31H24Cl2N2S2, the pyrazole ring adopts planar conformation with a maximum deviation of 0.002 (2) Å. The chlorophenyl rings are twisted out of the plane of the pyrazole ring by 75.1 (1) and 39.5 (1)°. The crystal packing is controlled by weak intermolecular C—H⋯π interactions
5-(2-Nitro-1-phenylbutyl)-4-phenyl-1,2,3-selenadiazole
In the title compound, C18H17N3O2Se, the selenadiazole ring is planar [maximum deviation = 0.012 (2) Å for the ring C atom bearing the phenyl substituent]. The dihedral angle between the selenadiazole ring and the attached benzene ring is 46.5 (1)°. There is one short intramolecular C—H⋯Se contact

1-(2-Naphthyl)-3-phenyl-3-(4,5,6,7-tetrahydro-1,2,3-benzoselenadiazol-4-yl)propan-1-one
In the title compound, C25H22N2OSe, the fused six-membered cyclohexene ring of the 4,5,6,7-tetrahydro-1,2,3-benzoselenadiazole group adopts a near half-chair conformation and the five-membered 1,2,3-selenadiazole ring is essentially planar (r.m.s. deviation = 0.004 Å). There are weak intermolecular C—H⋯O and C—H⋯π interactions in the crystal structure. Intermolecular π–π stacking is also observed between the naphthyl units, with a centroid–centroid distance of 3.529 (15) Å
Diethyl 2-[(4-nitrophenyl)(4-phenyl-1,2,3-selenadiazol-5-yl)methyl]malonate
In the title compound, C22H21N3O6Se, the heterocyclic ring makes dihedral angles of 50.03 (11) and 67.75 (11)°, respectively, with the benzene and phenyl rings. The terminal C atoms of the ester groups are disordered over two positions: the site occupancies for the C atoms are 0.62 (3)/0.38 (3) and 0.48 (3)/0.52 (3).
