Tetraphenylpentalenide organolanthanide complexes
Lanthanide sandwiches of the D 2h 1,3,4,6-tetraphenylpentalenide are reported. The Ph 4 Pn dianion shows promise for new electron-rich f-block organometallics using the metal's d z 2 orbital, in contrast to the more widely used cyclooctatetraenyl dianion.
