Abstract

The redox chemistry between divalent lanthanide complexes bearing bulky amidinate ligands has been studied with 3d transition metal carbonyl complexes (iron and cobalt). The reaction of [(DippForm)₂Sm^II(thf)₂] (DippForm =N,N′-bis(2,6-diisopropylphenyl)formamidinate) with [Co₂(CO)₈] resulted in the formation of a tetranuclear Sm-Co complex, [{(DippForm)₂Sm^III(thf)}₂{(μ-CO)₂Co(CO)₂}₂]. The product of the reaction of [(DippForm)₂Yb^II(thf)₂] and [Co₂(CO)₈] gives the dinuclear Yb-Co complex [{(DippForm)₂Yb^III(thf)}{(μ-CO)Co(CO)₃}] in toluene. The reaction of [(DippForm)₂Sm^II(thf)₂] was also carried with the neighbouring group 8 carbonyl complexes [Fe₂(CO)₉] and [Fe₃(CO)₁₂], resulting in a pentanuclear Sm^III-Fe complex, [{(DippForm)₂Sm^III}₂{(μ₃-CO)₂Fe₃(CO)₉}], featuring a triangular iron carbonyl cluster core.
