    • As the cage C(1) atom in 5 (or C(1') atom in 6) is formally six-coordinated, the Cahn-Ingold-Prelog notation seems to be not applicable for the assignment of absolute configuration of these centers. Nevertheless, while naming the enantiomers of 5 and 6 (Figures 2 and 3), we used the extension of Cahn-Ingold-Prelog rules, which takes advantage of the fact that all of the B(4), B(5), or B(6) atoms are on the same side of the Ru(1), C(13), B(3) triangle, and any of the former boron atoms, if treated as the fourth position on the tetrahedron, should be considered as the lowest priority substituent at the chiral C(1) center.
