The title compound, [Mn(C₁₀H₆NO₂)₂(CH₄O)₂], was obtained unintentionally as the product of an attempt to synthesize a polynuclear carboxyl­ate bridged manganese(III/IV) complex, using methanol to reduce the permanganate ion. The mol­ecule is centrosymmetric; the pairs of equivalent ligands coordinate trans to each other in a distorted octa­hedral geometry. Intra­molecular C—H⋯O bonds lying in the equatorial plane stabilize the mol­ecule. In the crystal, mol­ecules are linked by O—H⋯O and C—H⋯O hydrogen bonds, creating a three-dimensional supra­molecular structure. π–π and C—H⋯π inter­actions are also observed. The dihedral angle and centroid-to-centroid distance between the pyridine ring (A) and the benzene ring (Bⁱ) of a symmetrically related mol­ecule [symmetry code: (i) −1 − x, −y, −z] are 1.27 (11)° and 3.974 (2) Å, respectively. For the C—H⋯π inter­actions, the relevant distances and angles are: C⋯Cg[Aⁱⁱ] = 3.643 (2) Å, H⋯Cg[Aⁱⁱ] = 2.750 (2) Å and C—H⋯Cg[Aⁱⁱ] = 155 (1)° [symmetry code: (ii) x, −1 + y, z].
