Abstract
In the title compound, [PdBr2(C10H8N2)]·CH2Cl2, the Pd2+ 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 intramolecular C—H⋯Br hydrogen bonds and pairs of complex molecules are assembled by intermolecular C—H⋯Br hydrogen bonds. These pairs are connected by additional C—H⋯Br hydrogen bonds, forming a layer structure extending parallel to (011). Intermolecular π–π interactions between the pyridine rings of the ligand are also present, the shortest centroid–centroid distance being 4.090 (9) Å.
