μ-Oxido-bis­[(5,10,15,20-tetra­phenyl­porphyrinato-κ(4) N,N′,N′′,N′′′)manganese(III)]

In the crystal structure of the title oxido-bridged binuclear complex, [Mn(III)(TPP)](2)O (TPP = tetra­phenyl­porphyrinate, C(44)H(28)N(4)) or [Mn(2)(C(44)H(28)N(4))(2)O], the two penta­coordinate manganese(III) ions are bridged by a single oxido ligand, with an Mn—O distance of 1.7600 (3) Å and an Mn—O—Mn bridging angle of 176.1 (2)°. The bridging O(2−) ligand is located on a twofold rotation axis, resulting in point group 2 for the entire complex. The Mn(III) atom is displaced out of the 24-atom mean plane of the porphyrine entity by 0.52 Å. C—H⋯π and π–π inter­actions help to stabilize the mol­ecular packing within the crystal structure.
