Abstract: The title compound, [Cd₂Br₄(C₂₄H₁₆N₂)₂], consists of a centrosymmetric dimeric unit in which two Br atoms bridge two Cd^II atoms, forming a four-membered ring. A terminal Br atom and a bidentate chelating 4,7-diphenyl-1,10-phenanthroline ligand complete a square-pyramidal geometry for the Cd^II atom. In the crystal, C-HBr hydrogen bonds and - contacts between the pyridine and phenyl rings [centroid-centroid distances = 3.704 (4) and 3.715 (4) Å] lead to a three-dimensional supramolecular structure.
