μ-Oxido-bis-[(5,10,15,20-tetra-phenyl-porphyrinato-κ⁴ N,N',N'',N''')manganese(III)].

ABSTRACT: In the crystal structure of the title oxido-bridged binuclear complex, [Mn^III(TPP)]₂O (TPP = tetra-phenyl-porphyrinate, C₄₄H₂₈N₄) or [Mn₂(C₄₄H₂₈N₄)₂O], the two penta-coordinate 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 inter-actions help to stabilize the mol-ecular packing within the crystal structure.
