In the title compound, [PdBr(2)(C(10)H(8)N(2))]·CH(2)Cl(2), the Pd(2+) ion is four-coordinated in a slightly distorted square-planar environment by two N atoms of the chelating 2,2'-bipyridine ligand and two bromide ions. The compound displays intra-molecular C-H⋯Br hydrogen bonds and pairs of complex mol-ecules are assembled by inter-molecular C-H⋯Br hydrogen bonds. These pairs are connected by additional C-H⋯Br hydrogen bonds, forming a layer structure extending parallel to (011). Inter-molecular π-π inter-actions between the pyridine rings of the ligand are also present, the shortest centroid-centroid distance being 4.090 (9) Å.
在标题化合物[PdBr₂(C₁₀H₈N₂)]·CH₂Cl₂中,Pd²⁺离子在略微扭曲的平面正方形环境中通过螯合的2,2'-联吡啶配体的两个N原子和两个溴离子进行四配位。该化合物表现出分子内C—H⋯Br氢键,并且通过分子间C—H⋯Br氢键组装成双分子对。这些双分子对通过额外的C—H⋯Br氢键相连,形成平行于(011)延伸的层状结构。配体吡啶环之间还存在分子间π-π相互作用,最短质心-质心距离为4.090 (9) Å。
