标题化合物的不对称单元[Pd2(C9H12NSe)2Cl2]·0.5CH2Cl2包含两个半分子，每个半分子位于双轴上；每个分子都是手性的，具有相同的对映体。这只有在分子的Pd2+配位球呈铰链式顺式排列时才有可能。对于这种铰接二聚体结构，每个分子中两个配位面夹角分别为15.02(5)°和14.91(5)°。这种铰接的顺式排列还允许两个分子通过相邻分子的Pd和Se原子[3.4307(9)和3.4317 (9)Å]之间的二级相互作用形成对，从而形成整体的四聚体结构。在精制过程中，发现二氯甲烷溶剂分子沿双轴方向呈无序分布。在进行了不成功的建模尝试后，使用SQUEEZE将它们删除。
The asymmetric unit of the title compound, [Pd2(C9H12NSe)2Cl2]·0.5CH2Cl2, contains two half-molecules, each lying on a twofold axis; each molecule is chiral and of the same enantiomer. This is only possible as the molecule has a hinged cis arrangement about the Pd2+ coordination spheres. For this hinged dimeric structure, the angles between the two coordination planes in each molecule are 15.02 (5) and 14.91 (5)°. This hinged cis arragement also allows the two molecules to form pairs linked by secondary interactions between the Pd and Se atoms [3.4307 (9) and 3.4317 (9) Å] of adjoining molecules, leading to an overall tetrameric structure. During the refinement stages, it was noticed that there were dichloromethane solvent molecules present disordered about a twofold axis. After unsuccessful attempts were made to model this, they were removed using SQUEEZE.
