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.
已使用3d过渡金属羰基配合物（铁和钴）研究了带有庞大脒基配体的二价镧系配合物之间的氧化还原化学。[(DippForm)Sm(thf)]（DippForm = N,N'-双(2,6-二异丙基苯基)甲脒基）与[Co(CO)]反应生成四核Sm-Co配合物[{(DippForm)Sm(thf)}{(μ-CO)Co(CO)}]。[(DippForm)Yb(thf)]与[Co(CO)]反应的产物在甲苯中生成双核Yb-Co配合物[{(DippForm)Yb(thf)}{(μ-CO)Co(CO)}]。[(DippForm)Sm(thf)]还与相邻的第8族羰基配合物[Fe(CO)]和[Fe(CO)]反应，生成五核Sm-Fe配合物[{(DippForm)Sm}{(μ-CO)Fe(CO)}]，其具有三角形铁羰基簇核。
