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

The crystal structure of solvated [Mn(TPP)(NO(3))] (TPP = 5,10,15,20-tetra-phenyl-porphyrinato, C(44)H(28)N(4)), [Mn(C(44)H(28)N(4)O(3))(NO(3))]·0.5C(6)H(14)·0.5C(6)H(6), 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)†à with the average Mn-Np distance being 2.011†(6)†à (where Np is a porphyrin N atom). The Mn-O bond length is 2.1246†(18)†à . 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.
