In the title complex, cis-[PtCl(2)(C(11)H(9)N)(2)], the Pt(II) ion is situated in a slightly distorted square-planar environment coordinated by two N atoms from two 2-phenyl-pyridine ligands and two Cl atoms. The two pyridyl planes are inclined with dihedral angles of 59.1 (2) and 61.84 (19)° with respect to the PtCl(2)N(2) plane. In the crystal, the complex mol-ecules display inter- and intra-molecular π-π stacking inter-actions, with centroid-centroid distances of 3.806 (5)-3.845 (5) Å, which form a one-dimensional column structure along the a axis.
