In the title compound, [MnBr(C(10)H(9)N(3))(2)(H(2)O)]Br, the Mn(II) ion is six-coordinated in a considerably distorted cis-N(4)BrO octa-hedral environment defined by four N atoms of two chelating di-2-pyridyl-amine (dpa) ligands, one Br(-) anion and one O atom of a water ligand. As a result of the different trans effects of Br, N and O atoms, the Mn-N bond trans to the Br atom is slightly longer than the Mn-N bond trans to the N or O atoms. In the crystal, the dpa ligands are not planar, the dihedral angles between the two pyridine rings being 29.2 (4) and 28.2 (3)°. The complex cations and the Br(-) anions are linked by inter-molecular O-H⋯Br and N-H⋯Br hydrogen bonds. Inter-molecular π-π inter-actions are present between the pyridine rings, with a centroid-centroid distance of 3.793 (4) Å.
在标题化合物[MnBr(C₁₀H₉N₃)₂(H₂O)]Br中，Mn(II)离子在由两个螯合二-2-吡啶胺（dpa）配体的四个N原子、一个Br⁻阴离子和一个水配体的O原子所定义的明显扭曲的顺式-N₄BrO八面体环境中呈六配位。由于Br、N和O原子的不同反位效应，与Br原子反位的Mn-N键比与N或O原子反位的Mn-N键略长。在晶体中，dpa配体不是平面的，两个吡啶环之间的二面角为29.2 (4)°和28.2 (3)°。配合物阳离子和Br⁻阴离子通过分子间O-H⋯Br和N-H⋯Br氢键相连。吡啶环之间存在分子间π-π相互作用，质心-质心距离为3.793 (4) Å。
