Abstract: The title compound, (C12H16N3O)[PtCl4]Cl, consists of a 4,4'-(1-aza­niumyl-2-hy­droxy­ethane-1,2-di­yl)dipyridinium trication, a square-planar tetra­chloridoplatinate(II) dianion and a chloride ion. In the cation, the pyridinium rings attached to the central 1-aza­niumyl-2-hy­droxy­ethane fragment have an anti conformation, as indicated by the central C-C-C-C torsion angle of -166.5 (6)°, and they are inclined to one another by 63.5 (4)°. In the crystal, the cations and anions are linked through N-H...Cl and O-H...Cl hydrogen bonds. There are also [pi]-[pi] contacts [centroid-centroid distances = 3.671 (4) and 3.851 (4) Å] and a number of C-H...Cl inter­actions present, consolidating the formation of a three-dimensional supra­molecular structure.
