The syntheses, structural, and magnetic characterization of three new organometallic Ce complexes stabilized by PyCp₂²⁻ (PyCp₂²⁻ = [2,6-(CH₂C₅H₃)₂C₅H₃N]²⁻) are reported. Complex 1 provides the first example of a crystallographically characterized unsupported Ce–Fe bond in a molecular compound. Results from IR spectroscopy and computational analyses suggest weaker Fe → Ce electron-donation than in a previously reported Dy–Fe bonded species.

寻求对镧系元素-过渡金属键的理解：第一个Ce-Fe键复合物的研究†

由PyCp ₂²⁻（PyCp ₂²⁻ = [2,6-（CH ₂ C ₅ H ₃）₂ C ₅ H ₃ N] ²⁻）稳定的三种新型有机金属Ce配合物的合成，结构和磁性表征为报告。配合物1提供了分子化合物中具有晶体学特征的无支撑Ce-Fe键的第一个例子。红外光谱和计算分析的结果表明，Fe→Ce电子给体比以前报道的Dy–Fe键合物种弱。
