title: Crystal structure of chlorido-(5,10,15,20-tetra-phenyl-porphyrinato-κ(4) N)manganese(III) 2-amino-pyridine disolvate.
abstract: 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.
