Abstract: The asymmetric unit of the title compound, (C12H16N3O)2[PdCl4]3, consists of a 4,4'-(1-azaniumyl-2-hydroxyethane-1,2-diyl)dipyridinium dication and one and a half tetrachloridopalladate(II) anions; the latter has inversion symmetry. In the cation, the pyridinium rings attached to the central 1-azaniumyl-2-hydroxyethane fragment show an anti conformation, as indicated by the central C-C-C-C torsion angle of -178.1 (4)°, and they are inclined to one another by 25.7 (2)°. 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 distance = 3.788 (3) Å] and a number of C-H...O and C-H...Cl interactions are present, consolidating the formation of a three-dimensional structure.
