Chem. Commun., 2024, 60,9749-9752 DOI: 10.1039/D4CC02570A, Communication Nicholas J. Katzer, Mandeep Kaur, Asmita Sen, Rupal Nimaiyar, Jochen Autschbach, Polly L. Arnold, Ulrich Hintermair Lanthanide sandwiches of the D2h 1,3,4,6-tetraphenylpentalenide are reported. The Ph4Pn dianion shows promise for new electron-rich f-block organometallics using the metal's dz2 orbital, in contrast to the more widely used cyclooctatetraenyl dianion.
