A new route to iron carbonyls has enabled synthesis of (57)Fe-labeled [NiFe] hydrogenase mimic (OC)3(57)Fe(pdt)Ni(dppe). Its study by nuclear resonance vibrational spectroscopy revealed Ni-(57)Fe vibrations, as confirmed by calculations. The modes are absent for (OC)3(57)Fe(pdt)Ni(dppe), which lacks Ni-(57)Fe bonding, underscoring the utility of the analyses in identifying metal-metal interactions.
一种制备羰基铁的新方法使得合成(57)Fe标记的[NiFe]氢化酶模拟物(OC)3(57)Fe(pdt)Ni(dppe)成为可能。通过核共振振动光谱对其进行的研究揭示了Ni-(57)Fe振动,计算结果证实了这一点。对于缺乏Ni-(57)Fe键的[(OC)3(57)Fe(pdt)Ni(dppe)]+,这些振动模式不存在,这突出了该分析方法在识别金属-金属相互作用方面的实用性。
