In the mol-ecule of the title compound, [HgBr(2)(C(10)H(9)N(3))], the Hg(II) atom is four-coordinated in a distorted tetra-hedral configuration by two N atoms from the chelating di-2-pyridylamine ligand and by two Br atoms. In the crystal structure, inter-molecular N-H⋯Br hydrogen bonds link the mol-ecules into centrosymmetric dimers. There are π-π contacts between the pyridine rings [centroid-centroid distances = 3.9662 (5) and 3.9321 (4) Å]. There also exists a C-H⋯π contact between the pyridine CH group and a pyridine ring.
在标题化合物[HgBr₂(C₁₀H₉N₃)]的分子中，Hg(II)原子由来自螯合二-2-吡啶胺配体的两个N原子和两个Br原子以扭曲的四面体构型进行四配位。在晶体结构中，分子间的N-H⋯Br氢键将分子连接成中心对称的二聚体。吡啶环之间存在π-π相互作用[质心-质心距离 = 3.9662 (5) 和 3.9321 (4) Å]。吡啶CH基团与吡啶环之间还存在C-H⋯π相互作用。
