Abstract

Abstract : To provide a better understanding of the recently published pure metalorganic Ni I species, [Ni(cod)2 ][Al(O R F )4 ] (1 ) [cod = 1, 5‐cyclooctadiene, R F = C(CF3 )3 ], further characterizations were performed and analyzed. Thus, the solvation of1 in THF was examined by EPR, surprisingly disclosing the initiation of a disproportionation reaction to [Ni II (THF)6 ][Al(O R F )4 ]2 (3 ) and Ni 0 . Further studies concerning the ability of1 to activate small molecules exhibit the formation of a remarkable [Ni3 S2 (cod)3 ] 2+ cluster (5 ) in an oxidation reaction with S8, while EPR measurements of the resulting product in a reaction with oxygen indicate a possible coordination of O2 . Single crystal X‐ray structures as well as spectroscopic analyses of3 and5 are described. Abstract :
