Synthesis and Characterization of the Linear Trinuclear Complexes [M(O2CCH3)6(biphme)2], M = Mn, Fe

A Mn3 chain bridged by four bidentate and two monodentate carboxylate ligands characterizes the MnII title complex 1. Unique features are the monodentate acetate bridges, which have a “dangling” oxygen atom that influences the molecular structure through weak interactions with the terminal Mn atoms.
