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

The Pd(II) atom in the complex cation of the title compound, [PdCl(C(21)H(16)N(4))]Cl, is coordinated by three N atoms derived from the terpyridine ligand and a chloride ion, which define a distorted PdClN(3) 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 inter­spersed with the chloride anions with stabilization provided by C—H⋯Cl inter­actions involving both Cl atoms, as well as π–π inter­actions [the closest inter­action of 3.489 (6) Å occurs between a chelate ring and a pyridyl residue].
