AI Article Synopsis
- The study investigates the redox reactions of divalent lanthanide complexes with bulky amidinate ligands and 3d transition metal carbonyl complexes like iron and cobalt.
- The reaction of a specific samarium complex with cobalt carbonyl yielded a tetranuclear complex, while a similar reaction with a ytterbium complex produced a dinuclear complex.
- Additionally, the samarium complex's interaction with iron carbonyl led to the formation of a pentanuclear complex that includes a triangular iron carbonyl cluster.
Article 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)Sm(thf)] (DippForm = N,N'-bis(2,6-diisopropylphenyl)formamidinate) with [Co(CO)] resulted in the formation of a tetranuclear Sm-Co complex, [{(DippForm)Sm(thf)}{(μ-CO)Co(CO)}]. The product of the reaction of [(DippForm)Yb(thf)] and [Co(CO)] gives the dinuclear Yb-Co complex [{(DippForm)Yb(thf)}{(μ-CO)Co(CO)}] in toluene. The reaction of [(DippForm)Sm(thf)] was also carried with the neighbouring group 8 carbonyl complexes [Fe(CO)] and [Fe(CO)], resulting in a pentanuclear Sm-Fe complex, [{(DippForm)Sm}{(μ-CO)Fe(CO)}], featuring a triangular iron carbonyl cluster core.
