Reduced {Fe(NO)2} complexes are formed by reaction of Fe(CO)2(NO)2 with Ni(N2S2) (N2S2 = N,N'-Bis(2-mercaptoethyl)-1,4-diazacycloheptane (bme-dach) and N,N'-Bis(2-mercaptoethyl)-1,5-diazacyclooctane (bme-daco)). A single CO is replaced, yielding [Ni(N2S2)]Fe(NO)2(CO); however, with N2S2 = bme-dach, excess of Fe(NO)2(CO)2 leads to a cluster of core compn. Ni2S4Fe3 with triply bridging thiolate sulfurs. In the...
