[4′-(4-Aminophenyl)-2,2′:6′,2′′-terpyridine] chloridopalladium(II) chloride

Abstract

The PdII atom in the complex cation of the title compound, [PdCl(C21H16N4)]Cl, is coordinated by three N atoms derived from the terpyridine ligand and a chloride ion, which define a distorted PdClN3 square-planar coordination geometry. In the crystal, the presence of N - H⋯Cl hydrogen bonds involving the amino H atom and chloride anions link two cations and two anions into a four-ion aggregate via centrosymmetric eight-membered [⋯H - N - H⋯Cl]2 synthons. Layers of cations are inter-spersed with the chloride anions with stabilization provided by C - H⋯Cl inter-actions involving both Cl atoms, as well as π-π inter-actions [the closest inter-action of 3.489 (6) Å occurs between a chelate ring and a pyridyl residue].
