Subicosahedral carboranes

Polyhedral carboranes (continued) seven-vertex carboranes, 3, 58 six-vertex carboranes, 3, 56 small carborane syntheses, 3, 54 subicosahedral carborane geometrical patterns, 3, 50 subicosahedral and icosahedral, 3, 51 supraicosahedral, characteristics, 3, 96 ten-vertex carboranes, 3, 60 thirteen-vertex carboranes, 3, 100 tricarbaborane synthesis, 3, 54 twelve-vertex carboranes, 3, 98 Polyhedral skeletal electron pair theory, Ru and Os tetranuclear clusters, 6, 874-875 Poly(iV-heterocyclic carbene) ligands... 

Unlike the subicosahedral geometrical pattern, the supraicosahedral pattern is complex as shown in Figure 13 (COMC (1982) 5.4.2.7.2 and COMC (1995) 6.2.3.1, 6.2.4.4 and 6.2.5.1). For example, there are eight distinct geometries known with a nido-12-vertex count. This pattern is expected to expand further as the interest in 13-and 14-vertex closo-carboranes, which were only identified in the last three years, grows.
