Cluster borane paradigm

Mixed ligated/naked-atom clusters, which Schnockel has depicted as elementoid or metalloid, are clusters with internal as well as surface atoms. They illustrate the generalized cluster shown in Figure 2.1 and follow neither the borane paradigm nor... [Pg.73]

The number of cluster valence electrons is 66. Based on the examples of metalloid clusters in the text, we don t expect the borane paradigm to work for this closed cluster and it does not (An + 2 = 58 eve). It can be viewed as a hexacapped three-connect (highly distorted) cube giving, via the cluster fusion rule 5 x 8 + 6 x 24 — 6 x 24 [or — 6 x 22] = 40 [or 52] eve. This doesn t work and besides, four of the cube edges have very long Sn-Sn contacts. Finally, it can be viewed with the modified Schleyer approach (no lone pairs on Sn atoms) or the Schleyer approach... [Pg.356]
