In the title complex, [ZnCl2(C11H9N5)], the ZnII ion assumes a distorted trigonal-bipyramidal ZnN3Cl2 coordination geometry [Zn-N = 2.1397 (16)-2.2117 (17) Å, Zn-Cl = 2.2470 (6) and 2.2564 (6) Å]. The crystal packing exhibits [pi]-[pi] stacking interactions between the 2,6-dipyrazol-1-ylpyridine ligands of neighbouring molecules.
