Abstract

The crystal structure of solvated [Mn(TPP)(NO₃)] (TPP = 5,10,15,20-tetra-phenyl-porphyrinato, C₄₄H₂₈N₄), [Mn(C₄₄H₂₈N₄O₃)(NO₃)]·0.5C₆H₁₄·0.5C₆H₆, has been determined in the space group Pccn. The Mn^III atom has a distorted square-pyramidal environment, being coordinated by four pyrrole N atoms of the porphyrin ligand in the basal plane and an O atom of the nitrato ligand in the apical site. The Mn^III atom is displaced out of the porphyrin plane by 0.22 (4) Å with the average Mn-Np distance being 2.011 (6) Å (where Np is a porphyrin N atom). The Mn-O bond length is 2.1246 (18) Å. Two kinds of inter-molecular C-H⋯O hydrogen bonds exist in the crystal structure, with the apical nitrato ligands inter-acting with solvent mol-ecules and adjacent mol-ecules, respectively.
