Carboranes seven-vertex

Figure 1 shows the known experimental geometries of carboranes. For discussion of closo-, nido-, and arachno-zlectron counts and their expected geometries, see COMC (1982) 5.4.2.2 and 5.4.2.3. Arachno-six- and seven-vertex geometries are not known experimentally for carboranes.
