Heteronukleare Komplexverbindungen mit Metall—Metall-Bindungen. VIII. Neue heterodinukleare Komplexe mit Bindungen zwischen Kupfer(I) und Mangan(–I), Eisen(–I) oder Cobalt(–I)

Heteronuclear Coordination Compounds with Metal—Metal Bonds. VIII. New Heterodinuclear Complexes with Bonds between Copper(I) and Manganese(?I), Iron(?I), or Cobalt(?I) (en)Cu? Mn(CO)₅] ( 1a ), (dien)Cu? Mn(CO)₅] ( 1b ), (en)Cu? Fe(CO)₃(NO)] ( 2a ), (dien)Cu? Fe(CO)₃(NO)] ( 2b ), (en)Cu? Co(CO)₄] ( 3a ), and (dien)Cu? Co(CO)₄] ( 3b ) are new heterobinuclear metal—metal bonded complexes. The geometry of the Mn(CO)₅]^?, Fe(CO)₃(NO)]^?, and Co(CO)₄]^? ions is distorted only to a less extend in accord with a heteropolar bond to copper.
