Abstract
The X-ray structure analysis of bis(8-dimethylamino-1-naphthyl)phenylp hosphane (3) and of the corresponding sulphide 4 has revealed hexacoor dination at phosphorus in both cases, the N ... P separations being le ss than the sum of the van der Waal radii. Furthermore, in both cases the overall geometry corresponds to a distorted bicapped tetrahedron. The optimum geometry calculated for 4 via the HYPERCHEM program develo ped by Autodesk (MM + method) suggests that the structure of the molec ule is a function not only of steric requirements but also of electron ic effects.
