“…Carborane 36 is the compound on which the first two-dimensional NMR study in the area of boroncluster compounds was performed.67® Durso et al 176 have recently used microwave techniques to determine the structure and dipole moment of 5-F-doso-2,4-C2B5H6 (for structure see 36). They found that the interboron distances are comparable with those obtained for the parent compound1,5 and the relatively short B-F distance (133.0 (3) pm) was interpreted in terms of partial double-bond character.…”
