The compound is a colorless polycrystalline material, decomposition temperature 200°, that is insoluble in all nonpolar organic solvents. It is, however, quickly soluble in water and alcohols, followed by solvolysis. In acidic medium, mercury halides and phosphonium halides are formed in quantitative yields. [Pg.141]

An isoelectronic cation, [Au[CH2P(CH3)3] 2], has also been reported and was shown to exhibit similar properties. Zinc and cadmium halides form polymeric materials with the ylide. [Pg.141]
