Zusammenfassung
A review contg. 37 refs. The capability of the title fragment to undergo efficient p back bonding, to exist in two kinetically stable neighboring oxidn. states, and to exhibit a relatively small ligand field splitting allow the formation of unusual coordination compds. Several mono- and polynuclear examples with an odd or even electron count and different degrees and direction of electron delocalization between ligand and metal fragment(s) are discussed.
