报道了新的杂化双（膦）（吡唑）硼酸盐三脚架配体（[PhBPtBu 2（pz ′）]-），其支持氧化态为+1、+2、+3和+4的假四面体铁。较高的氧化态通过末端FeNR键稳定。特别感兴趣的是使用这种新的配体系统的S = 1 FeIVNR+酰亚胺阳离子的生成和彻底表征。后者的物种可以观察到电化学和光谱，其固态晶体结构的报告。
New hybrid bis(phosphine)(pyrazole)borate tripodal ligands ([PhBPtBu2(pz')]-) are reported that support pseudotetrahedral iron in the oxidation states +1, +2, +3, and +4. The higher oxidation states are stabilized by a terminal FeNR linkage. Of particular interest is the generation and thorough characterization of an S = 1 FeIVNR+ imide cation using this new ligand system. The latter species can be observed electrochemically and spectroscopically, and its solid-state crystal structure is reported.
