Crystal structure and Hirshfeld surface analysis of di­chlorido­[2-(3-cyclo­pentyl-1,2,4-triazol-5-yl-κN4)pyridine-κN]palladium(II) di­methyl­formamide monosolvate

Abstract

The crystal structure of mononuclear di­chlorido­palladium(II) complex with 2-(3-cyclo­pentyl-1,2,4-triazol-5-yl)pyridine is reported and discussed.

This study presents the synthesis, characterization and Hirshfeld surface analysis of the title mononuclear complex, [PdCl₂(C₁₂H₁₄N₄)]·C₃H₇NO. The compound crystalizes in the P2₁/c space group of the monoclinic system. The asymmetric unit contains one neutral complex Pd(HL^c-Pe)Cl₂ [HL^c-Pe is 2-(3-cyclo­pentyl-1,2,4-triazol-5-yl)pyridine] and one mol­ecule of DMF as a solvate. The Pd atom has a square-planar coordination. In the crystal, mol­ecules are linked by inter­molecular N—H⋯O and C—H⋯N hydrogen bonds, forming layers parallel to the bc plane. A Hirshfeld surface analysis showed that the H⋯H contacts dominate the crystal packing with a contribution of 41.4%. The contribution of the N⋯H/H⋯N and H⋯O/O⋯H inter­actions is somewhat smaller, amounting to 12.4% and 5%, respectively.
