The title compound, [Fe(C7H5O2)(2) (CH4O)(4)], is a centrosymmetric six-coordinate Fe-II complex coordinated by two axial monodentate benzoate ligands and four methanol ligands in the equatorial plane [Fe-O-benzoate 2.0935 (7) Angstrom, and Fe- O-methanol 2.1310 (7) and 2.1290 (7) Angstrom]. The benzoate ligands adopt monodentate ligation, rather than a bridged polymeric structure, because of strong intra- and intermolecular hydrogen bonds to the methanol ligands. This structure is nearly identical to that obtained with a much bulkier carboxylate ligand [Chavez, Que & Tolman (2001). Chem. Commun. pp. 111-112].
