Pentamethylcyclopentadienyllutetium Derivatives of Dimethylphosphoniobis(methanide)

Abstract

The first X-ray structure analysis of a lanthanoid-phosphorus ylide complex has been carried out on the lutetium derivative 1. Compound 1, which is extremely sensitive to air and moisture, was synthesized from (C5Me5)2LuCl2Na(Et2O)2 and Li(CH2)2P(CH3)2.
