用 2 或 3 当量的膦处理 [Fe(BH4)(CyPNP)]（CyPNP = 双（二环己基膦甲基）吡咯）分别得到八面体低自旋氢化铁化合物 [FeH(PMe2Ph)(N2)(CyPNP)] 和 [FeH(PMe3)2(CyPNP)]。这些新的氢化物以及之前报道的 [FeMe(CyPNP)] 与硅烷反应形成一类新型方形平面、中间自旋 (S = 1) 铁硅烷基络合物 [Fe(SiRPh2)(CyPNP)] (R = H、Me、F)。空间位阻较大的氢化铁 [FeH(tBuPNP)]（tBuPNP = 双（二叔丁基膦甲基）吡咯）也可通过 PhSiH3 处理来分离 [Fe(SiH2Ph)(tBuPNP)]。 [Fe(SiRPh2)(CyPNP)]在分子氮气氛下与低自旋[Fe(N2)(SiRPh2)(CyPNP)]存在平衡，而[Fe(SiH2Ph)(tBuPNP)]则不然。将 CO 气氛引入到 [Fe(SiHPh2)(CyPNP)] 中，产生八面体反式二羰基物质 [Fe(CO)2(SiHPh2)(CyPNP)]，但除去该气氛会导致失去一个 CO，从而形成方形锥体络合物……
Treatment of [Fe(BH4)(CyPNP)] (CyPNP = bis(dicyclohexylphosphinomethyl)pyrrole) with 2 or 3 equiv of phosphine afforded the octahedral low-spin iron hydride compounds [FeH(PMe2Ph)(N2)(CyPNP)] and [FeH(PMe3)2(CyPNP)], respectively. These new hydrides, as well as the previously reported [FeMe(CyPNP)], react with silanes to form a new class of square-planar, intermediate-spin (S = 1) iron silyl complexes, [Fe(SiRPh2)(CyPNP)] (R = H, Me, F). The more sterically encumbered iron hydride [FeH(tBuPNP)] (tBuPNP = bis(di-tert-butylphosphinomethyl)pyrrole) was also employed to isolate [Fe(SiH2Ph)(tBuPNP)] via treatment with PhSiH3. [Fe(SiRPh2)(CyPNP)] exists in an equilibrium with low-spin [Fe(N2)(SiRPh2)(CyPNP)] under an atmosphere of molecular nitrogen, whereas [Fe(SiH2Ph)(tBuPNP)] does not. Introducing an atmosphere of CO to [Fe(SiHPh2)(CyPNP)] yielded the octahedral trans-dicarbonyl species [Fe(CO)2(SiHPh2)(CyPNP)], but removal of that atmosphere resulted in loss of one CO to afford the square-pyramidal complex ...
