title: Bis[(1RS,2RS)-4,4'-(1-aza-niumyl-2-hy-droxy-ethane-1,2-di-yl)dipyridinium] tris-[tetra-chloridopalladate(II)].
abstract: The asymmetric unit of the title compound, (C12H16N3O)2[PdCl4]3, consists of a 4,4'-(1-aza-niumyl-2-hy-droxy-ethane-1,2-di-yl)dipyridinium dication and one and a half tetra-chloridopalladate(II) anions; the latter has inversion symmetry. In the cation, the pyridinium rings attached to the central 1-aza-niumyl-2-hy-droxy-ethane 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 π-π contacts [centroid-centroid distance = 3.788 (3) Å] and a number of C-H⋯O and C-H⋯Cl inter-actions are present, consolidating the formation of a three-dimensional structure.
