Direct synthesis of organophosphorus compounds from white phosphorus (P4) is of great significance because this process avoids the industry pollution synthetic methods and provides the possibilities for many novel phosphorus-containing compounds. A trinuclear rare-earth metal complex[{(η5-C5Me5)LuCl}3(THF)P6] [Li(THF)4] from lutetacyclopentadiene mediated P4 functionalization was isolated and characterized. This novel complex contains a bicyclo[3.1.0]-P64- ligand which is an unreported type. X-ray diffraction analysis shows that the bicyclo[3.1.0]-P64- ligand adopts a boat-like conformation. Three lutetium atoms coordinate to this ligand in η1, η3, η3 mode, respectively, and a novel[P6Lu3] cage has been formed. Density functional theory (DFT) calculations indicate that there are two three-center two-electron bonds.

Key words: polyphosphorus ligand, white phosphorus activation, rare-earth-metal complex
