Towards understanding of lanthanide–transition metal bonding: investigations of the first Ce–Fe bonded complex†
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.
