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-HCl and O-HCl hydrogen bonds. There are also - contacts [centroid-centroid distances = 3.671 (4) and 3.851 (4) Å] and a number of C-HCl interactions present, consolidating the formation of a three-dimensional supramolecular structure.
