Crystal structure and Hirshfeld surface analysis of di-chlorido-[2-(3-cyclo-pentyl-1,2,4-triazol-5-yl-kN4)pyridine-kN]palladium(II) di-methyl-formamide monosolvate

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-cyclo-pentyl-1,2,4-triazol-5-yl)pyridine] and one mol-ecule of DMF as a solvate. The Pd atom has a square-planar coordination. In the crystal, mol-ecules are linked by inter-molecular 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 inter-actions is somewhat smaller, amounting to 12.4% and 5%, respectively.
