Synthesis, crystal structure and Hirshfeld analysis of trans-bis­{(2E)-N-phenyl-2-[(2E)-3-phenyl-2-propen-1-yl­idene]hydrazinecarbo­thio­amidato-κ(2) N (1),S}palladium(II)

The reaction of (2E)-N-phenyl-2-[(2E)-3-phenyl-2-propen-1-yl­idene]hydra­zine­carbo­thio­amide (common name: cinnamaldehyde-4-phenyl­thio­semi­carbazone) deprotonated with NaOH in ethanol with an ethano­lic suspension of Pd(II) chloride in a 2:1 molar ratio yielded the title compound, [Pd(C(16)H(14)N(3)S)(2)]. The anionic ligands act as metal chelators, κ(2) N (1) S-donors, forming five-membered rings with a trans-configuration. The Pd(II) ion is fourfold coordinated in a slightly distorted square-planar geometry. For each ligand, one H⋯S and one H⋯N intra­molecular inter­actions are observed, with S(5) and S(6) graph-set motifs. Concerning the H⋯S inter­actions, the coordination sphere resembles a hydrogen-bonded macrocyclic environment-type. In the crystal, the complexes are linked via pairs of H⋯S inter­actions, with graph-set motif R (2) (2)(8), and building a mono-periodic hydrogen-bonded ribbon along [001]. The Hirshfeld surface analysis indicates that the major contributions for the crystal cohesion are: H⋯H (45.3%), H⋯C/C⋯H (28.0%), H⋯S/S⋯H (8.0%) and H⋯N/N⋯H (7.4%).
