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)(2)Sm-II(thf)(2)] (DippForm = N,N '-bis(2,6-diisopropylphenyl)formamidinate) with [Co-2(CO)(8)] resulted in the formation of a tetranuclear Sm-Co complex, [{(DippForm)(2)Sm-III(thf)}(2){(mu-CO)(2)Co(CO)(2)}2]. The product of the reaction of [(DippForm)(2)Yb-II(thf)(2)] and [Co-2(CO)(8)] gives the dinuclear Yb-Co complex [{(DippForm)(2)Yb-III(thf)}{(mu-CO)Co(CO)(3)}] in toluene. The reaction of [(DippForm)(2)Sm-II(thf)(2)] was also carried with the neighbouring group 8 carbonyl complexes [Fe-2(CO)(9)] and [Fe-3(CO)(12)], resulting in a pentanuclear Sm-III-Fe complex, [{(DippForm)(2)Sm-III}(2){(mu(3)-CO)(2)Fe-3(CO)(9)}], featuring a triangular iron carbonyl cluster core.
