The complete mol-ecule of the title compound, [MnCl(2)(C(18)H(10)N(4))(2)], is generated by crystallographic twofold symmetry with the Mn atom lying on the rotation axis. The Mn coordination geometry is a distorted cis-MnCl(2)N(4) octa-hedron, arising from two N,N'-bidentate dipyrido[3,2-a:2',3'-c]phenazine (DPPZ) ligands and two chloride ions. In the crystal structure, neighbouring mononuclear units pack together through π-π contacts between the DPPZ rings [shortest centroid-centroid distance = 3.480 (2) Å], leading to a chain-like structure along [001]. C-H⋯Cl hydrogen bonds complete the structure.
标题化合物[MnCl₂(C₁₈H₁₀N₄)₂]的完整分子通过晶体学二重对称性生成，锰原子位于旋转轴上。锰的配位几何形状是一个扭曲的顺式MnCl₂N₄八面体，由两个N,N'-双齿二吡啶并[3,2-a:2',3'-c]吩嗪（DPPZ）配体和两个氯离子形成。在晶体结构中，相邻的单核单元通过DPPZ环之间的π-π接触堆积在一起[最短质心-质心距离 = 3.480 (2) Å]，沿[001]方向形成链状结构。C-H⋯Cl氢键完善了该结构。
