In the title compound, [Mn(C44H28N4)Cl]·2C5H6N2, the Mn(III) centre is coordinated by four pyrrole N atoms [averaged Mn-N = 2.012 (4) Å] of the tetra-phenyl-porphyrin mol-ecule and one chloride axial ligand [Mn-Cl = 2.4315 (7) Å] in a square-pyramidal geometry. The porphyrin macrocycle exhibits a non-planar conformation with major ruffling and saddling distortions. In the crystal, two independent solvent mol-ecules form dimers through N-H⋯N hydrogen bonding. In these dimers, one amino N atom has a short Mn⋯N contact of 2.642 (1) Å thus completing the Mn environment in the form of a distorted octa-hedron, and another amino atom generates weak N-H⋯Cl hydrogen bonds, which link further all mol-ecules into chains along the a axis.
在标题化合物[Mn(C₄₄H₂₈N₄)Cl]·2C₅H₆N₂中,Mn(III)中心由四苯基卟啉分子的四个吡咯N原子[平均Mn-N = 2.012 (4) Å]和一个氯化物轴向配体[Mn-Cl = 2.4315 (7) Å]以四方锥几何构型配位。卟啉大环呈现出具有主要褶皱和鞍形畸变的非平面构象。在晶体中,两个独立的溶剂分子通过N-H⋯N氢键形成二聚体。在这些二聚体中,一个氨基N原子与Mn有2.642 (1) Å的短接触,从而以扭曲八面体的形式完成了Mn的配位环境,另一个氨基原子形成弱N-H⋯Cl氢键,这些氢键进一步将所有分子沿a轴连接成链。
