Abstract

original image

The PCP angle in crystalline carbodiphosphoranes and the triboluminescence shown by some modifications, e.g. of Ph3PCPPH3 have been thought to be related for some time. The search for further outstanding structural features has now led to a deeper understanding of this phenomenon and also showed that the bonding in MePh2PCPPh2Me is far better explained in terms of the polar (A) than by the nonpolar from (B).
