In the title compound, [ZnI2(C17H20N2)2], the ZnII atom is four-coordinated by two I atoms and the N atoms of two pyridine rings belonging to different ligands in a distorted tetrahedral geometry. The coordinating pyridine rings are oriented in an almost perpendicular fashion, making a dihedral angle of 83.7 (5)°.
