Towards understanding of lanthanide-transition metal bonding: investigations of the first Ce-Fe bonded complex

Chem Commun (Camb). 2018 Sep 25;54(77):10893-10896. doi: 10.1039/c8cc05243c.

Abstract

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.
