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.
标题化合物(C12H16N3O)2[PdCl4]3的不对称单元由一个4,4'-(1-氮杂-2-羟基乙烷-1,2-二亚基)二吡啶鎓二价阳离子和一个半四氯钯酸(II)阴离子组成；后者具有反演对称性。在阳离子中，与中心1-氮杂-2-羟基乙烷片段相连的吡啶鎓环呈反式构象，中心C-C-C-C扭转角为-178.1 (4)°表明了这一点，且它们彼此间倾斜25.7 (2)°。在晶体中，阳离子和阴离子通过N-H⋯Cl和O-H⋯Cl氢键相连。还存在π-π接触[质心-质心距离 = 3.788 (3) Å]，并且存在许多C-H⋯O和C-H⋯Cl相互作用，巩固了三维结构的形成。
