Crystal structure of bis­­(μ-4-nitro­benzoato-κ2O:O′)bis­­[bis­­(4-methyl­pyridine-κN)(4-nitro­benzoato-κ2O,O′)manganese(II)]

The title compound, [Mn2(C7H4NO4)4(C6H7N)4] or [Mn2(μ-NBz)2(κ2-NBz)2(4-Mepy)4], where NBz is 4-nitro­benzoate and 4-Mepy is 4-methyl­pyridine, is a centrosymmetric dinuclear complex in which the MnII atoms are bridged by two NBz ligands with Mn⋯Mn = 4.1324 (4) Å. The MnII atom in this dimeric species is present in a distorted octa­hedral environment with the four coordinating O atoms forming the equatorial plane and the two pyridyl N atoms occupying the axial sites. An important structural feature of the dimeric complex is that each of the bridging carboxyl­ate ligands binds to the metal ions in an asymmetric fashion involving bent and linear Mn—O—C units. The crystal packing is consolidated by C—H⋯O and C—H⋯π interactions.
