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-H⋯Br hydrogen bonds and π-π contacts between the pyridine and phenyl rings [centroid-centroid distances = 3.704 (4) and 3.715 (4) Å] lead to a three-dimensional supra-molecular structure.
标题化合物[Cd₂Br₄(C₂₄H₁₆N₂)₂]由一个中心对称的二聚体单元组成，其中两个溴原子桥连两个镉(II)原子，形成一个四元环。一个端基溴原子和一个双齿螯合的4,7-二苯基-1,10-菲咯啉配体为镉(II)原子构建了一个四方锥几何构型。在晶体中，C—H⋯Br氢键以及吡啶环与苯环之间的π-π接触[质心-质心距离 = 3.704 (4) 和3.715 (4) Å]导致形成三维超分子结构。
