Nitrato(5,10,15,20-tetra-phenyl-porphinato)manganese(III)-benzene-n-hexa-ne (2/1/1).

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 MnIII 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 MnIII 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.
