In the text of the paper ESI– MS and ESI⁺ MS should be as follows: HRESI^–-MS and HRESI⁺-MS, respectively. The text on p. 38 should be as follows: In the crystal structure of 19, the closo-decaborate cluster has a slightly distorted bicapped Archimedean antiprism geometry (see figure) [4, 5, 8]. Read “carbon” instead of “carbopn.” The text on p. 42 should be as follows: Compound 21.
