Tetrakis(μ-pivalato-κ2 O:O′)bis-[(2- methylpyridine-κN)iron(II)](Fe - Fe)

Abstract

The asymmetric unit of the title compound, [Fe2(C5H9O2)4(C6H7N)2], contains one unique Fe-atom site located close to a centre of symmetry which generates the mol-ecular dimer. The two Fe atoms are bridged by four carboxyl-ate groups and are each coordinated by a mol-ecule of 2-picoline. Electron counting and the 18-electron rule suggest that a chemical single bond is likely to exist between the two Fe atoms, which are separated by a distance of 2.8576 (4) Å. This bond completes an approximately octa-hedral coordination environment around each Fe atom.
