In the title complex, [MnCl(2)(C(10)H(9)N(3))(2)], the Mn(II) ion is six-coordinated in a considerably distorted cis-N(4)Cl(2) octa-hedral environment defined by four N atoms of two chelating di-2-pyridyl-amine (dpa) ligands and two Cl(-) anions. In the crystal, the dpa ligands are not planar, the dihedral angles between the two pyridine rings being 29.3 (2) and 30.9 (2)°. The complex mol-ecules are stacked in columns along the c axis and are connected by inter-molecular N-H⋯Cl hydrogen bonds, forming a three-dimensional network. Weak inter- and intra-molecular π-π inter-actions are present between the pyridine rings, the shortest centroid-centroid distance being 4.406 (3) Å.
在标题配合物[MnCl₂(C₁₀H₉N₃)₂]中，Mn(II)离子在由两个螯合二-2-吡啶胺（dpa）配体的四个N原子和两个Cl⁻阴离子所定义的严重扭曲的顺式-N₄Cl₂八面体环境中呈六配位。在晶体中，dpa配体不是平面的，两个吡啶环之间的二面角为29.3 (2)°和30.9 (2)°。配合物分子沿c轴堆积成列，并通过分子间N-H⋯Cl氢键相连，形成三维网络。吡啶环之间存在弱的分子间和分子内π-π相互作用，最短的质心-质心距离为4.406 (3) Å。
