Abstract
The [8,8'-μ-I-3-Co(1,2-C2B9H10)2] complex with a iodonium bridge between both dicarbollide ligands was prepared and its constitution was established by NMR methods. It behaves as a Lewis acid opening its bridge by the action of Lewis bases to form {8-I-8'-L-3-Co(1,2-C2B9H10)2] species. The less stable bromonium analogue was not isolated but its existence was confirmed by the reaction with Lewis bases affording the [8-Br-8'-L-3-Co(1,2-C2B9H10)2]derivatives.Keywords
