✦ Synopsis


The different reactivity of P,[Si(CH,),], (1) and P7(CH3), (2) is discussed in terms of a simple MO scheme. This scheme is based on semiempirical calculations (MIND0/3, MNDO) and on He(1) photoelectron spectroscopic investigations on 1 and 2. The electronic structure of similar cage compounds with the nortricyclane skeleton like P: -, P4S3, and P7[Si(CH3),], is compared with 1 and 2.

Das MO-Schema basiert auf semiempirischen Rechnungen (MIND013, MNDO) und auf He(1)-photoelektronenspektroskopischen Untersuchungen an 1 und 2. Die Elektronenstruktur ahnlich gebauter Kafigverbindungen mit Nortricyclangerust wie P73-, P,S, und P7[Si(CH3),l3 wird mit 1 und 2 verglichen.

The phosphorus compounds P4[Si(CH3)J3 (1) and P,(CH,), (2)') have been recently prepared and their structures have been determined by X-ray3) and NMR studies4). Both compounds show the nortricyclane skeleton and therefore one should expect similar donor properties at the basal and apical P centers.
