43. In Figure 1, the plane containing the apical borons (B(16) and B(26)), the unique borons (B(14) and B(24)), and the midpoint of the bond between the cage carbons.
44. Whenever an average value of a parameter is given, the indetermination listed is the average deviation.
45. Compound VI crystallized in the monoclinic space group C2 with a = 17.685 Å, b = 14.358 Å, c = 19.952 Å, and β = 93.59°. Because of disorder, the cage could only be partially refined and the data are not included.
46. Following normal usage, the facial boron that resides in the pseudomirror plane of the cage is the unique boron (B(14) in Figures 1-3), with the basal borons being the two off-plane atoms.
