The title compound, [ZnCl2(C21H15N3)], was obtained from the reaction of ZnCl2·4H2O with 4′-phenyl­terpyridine (L) and disodium 2,6-dipicolinate. The Zn2+ cation is ligated by the N atoms of the tridentate L ligand and two chloride anions, forming a ZnN3Cl2 polyhedron with a distorted trigonal–bipyramidal coordination geometry. In the crystal, nonclassical C—H⋯Cl hydrogen bonds are observed.
