Crystal structure of bis(triphenylphosphoranylidene)methane [hexaphenylcarbodiphosphorane, Ph3P:C:PPh3]

Abstract

The structure of the title compound has been determined. The crystals are monoclinic with a= 15·362, b= 9·483, c= 20·054 Å, β= 95° 6′, Z= 4, space group C2. 3292 Visually estimated X-ray reflections were refined to R 8·88%. There are two crystallographically independent molecules, each possessing a two-fold axis. The P[double bond, length as m-dash]C[double bond, length as m-dash]P angle is 143·8° in one of these molecules and 130·1° in the other. The results are compared with those obtained for related species, including the isoelectronic cation Ph3P[double bond, length as m-dash]N[double bond, length as m-dash]PPh3 and the cumulene ylides.
