✦ Synopsis

Three trinuclear complex anions, [(FeCi&hlS,]*-(M = MO, \V) and [(MoS&Fe13; were studied by MBssbauer and magnetic measurements. The results imply a high electron affinity of the MS:-group and intramolecular spin coupling These properties and structural features suggest these molecular groups as possible building blocks of the Fe-Ma co-factor of the nitrogen fixing enzyme nitrogenase.
