Electron counting main-group cluster fragments

Treat the metal cluster [RunHlCOh 2. with known metal core geometry shown below (a) as a cluster that obeys the counting rules for main-group clusters (b) as a fused cluster structure and (c) as a radial- and surface-bonded core cluster with external cluster fragments bound by radial bonds only. Which provides a satisfactory explanation at the level of electron counting ... [Pg.134]

In Chapter 2, a series of concepts and models for describing bonding in borane and metal cluster were analyzed. The most versatile of such descriptions appears to be those rules related with the Effective Atomic Number (EAN) and with the Skeleton Electron Pairs (SEP). As assumed in some of the rules described in Table 2.16, frequently main group element fragments are actually involved in cluster bonding so that they obey the same electron counting rules. [Pg.197]
