✦ Synopsis

Halogenation of nido-B 10 H 14 with C 2 H 2 Cl 4 , C 2 Cl 6 , Br 2 , or I 2 , produces by cluster degradation the (2 n)-closoclusters B 9 X 9 (X = Cl, Br, I). The synthesis of salts of the perhalogenated radical anions of the type (2 n + 1)-closo-[B 9 X 9 ] ´± and of the corresponding dianions (2 n + 2)-closo-[B 9 X 9 ] 2± from neutral B 9 X 9 is described [n is the number of cluster atoms; (2 n), (2 n + 1), and (2 n + 2) is the number of cluster electrons].
