With respect to the planar five-membered ring of the title compound, C(16)H(15)N(3)O(2)S, the phenyl ring is aligned at 47.0 (1)° and the phenyl-ene ring at 37.6 (1)°. The amino group has the N atom in a pyramidal geometry; the group is a hydrogen-bond donor to the sulfonyl O atom of one mol-ecule and to the pyrazole N atom of another mol-ecule, resulting in the formation of a layer parallel to the bc plane.

In the title compound, CHN·2CHNO, 4-nitro-phenol and 4,4'-bi-pyridine crystallized together in a 2:1 ratio in the space group 2/. There is a hydrogen-bonding inter-action between the nitro-gen atoms on the 4,4'-bi-pyridine mol-ecule and the hydrogen atom on the hydroxyl group on the 4-nitro-phenol, resulting in trimolecular units. This structure is a polymorph of a previously reported structure [Nayak & Pedireddi (2016 ▸).

This study presents the synthesis, characterization and Hirshfeld surface analysis of the title mononuclear complex, [PdCl(CHN)]·CHNO. The compound crystalizes in the 2/ space group of the monoclinic system. The asymmetric unit contains one neutral complex Pd(H )Cl [H is 2-(3-cyclo-pentyl-1,2,4-triazol-5-yl)pyridine] and one mol-ecule of DMF as a solvate.

The di-hydro-imidazole ring in the title mol-ecule, CHNOS, is slightly distorted and the lone pair on the tri-coordinate nitro-gen atom is involved in intra-ring π bonding. The methyl-sulfanyl substituent lies nearly in the plane of the five-membered ring while the ester substituent is rotated well out of that plane. In the crystal, C-H⋯O hydrogen bonds form inversion dimers, which are connected along the - and axis directions by additional C-H⋯O hydrogen bonds, forming layers parallel to the plane.
