Abstract: The magnetic properties of oxo-bridged oxo-(carboxylato)-bridged and oxo-bis(carboxylato)-bridged iron(III) dimers are found to depend on the iron-(m-O) distance as well as on the iron-(m-O)-iron angle. With an angular and radial overlap model we account for both these dependencies. The use of an angular overlap model allows us to separate the s donor properties of oxide as a ligand into the ss and ps contributions.
