Crystal structure of bis­(μ-4-nitro­benzoato-κ(2) O:O′)bis­[bis­(4-methyl­pyridine-κN)(4-nitro­benzoato-κ(2) O,O′)manganese(II)]

The title compound, [Mn(2)(C(7)H(4)NO(4))(4)(C(6)H(7)N)(4)] or [Mn(2)(μ-NBz)(2)(κ(2)-NBz)(2)(4-Mepy)(4)], where NBz is 4-nitro­benzoate and 4-Mepy is 4-methyl­pyridine, is a centrosymmetric dinuclear complex in which the Mn(II) atoms are bridged by two NBz ligands with Mn⋯Mn = 4.1324 (4) Å. The Mn(II) 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.
