Abstract

The cover picture shows the multiple characterization methods used to unravel the electronic and geometrical structures of the unit M~A~^III^M~B~^II^, in which three oximato groups (=N−O)^−^ are present as bridging ligands. Variable‐temperature magnetic susceptibility and EPR measurements provide a consistent answer to the question of electronic ground states for different heterometallic combinations. Mößbauer spectroscopy helps to differentiate between the species Co^III^(l.s.)Fe^II^(l.s.) and Fe^II^(h.s.)Co^III^(l.s.). Details on the preparation and characterization of the species Fe^III^M^II^ and related heterometallic compounds are presented in the article by P. Chaudhuri et al. on p. 4299 ff.
