Description	Preparative routes to 8-hydroxy-bis(1,2-dicarbollido)-3-cobalt(1-)ate (2) and 8,8 -dihydroxy-bis(1,2-dicarbollido)-3-cobalt(1-)ate (3) ions are reported by the reductive acetoxylation of the parent bis(dicarbollido)cobaltate ion (1) followed by hydrolysis of the intermediates. The essential reagent is acetic anhydride, and strong acids are required as catalysts. For the hydroxyderivative ion 2 the simultaneous presence of acetic acid brings benefit, whereas it is detrimental for the formation of the dihydroxyderivative 3. Reaction intermediate leading to the dihydroxy derivative is the already reported [8,8 - -CH3C(O)2(1,2-C2B9H10)2-3-Co]0 zwitterion. This compound was adequately characterised for the first time and its molecular structure as determined by X-ray diffraction analysis is presented. Both B-hydroxylated bis(dicarbollido)-ions can be alternatively obtained on the direct hydroxylation of the parent ion by hot 60-80 sulphuric acid. Optimised synthetic procedures and the main physicochemical Preparative routes to 8-hydroxy-bis(1,2-dicarbollido)-3-cobalt(1-)ate (2) and 8,8 -dihydroxy-bis(1,2-dicarbollido)-3-cobalt(1-)ate (3) ions are reported by the reductive acetoxylation of the parent bis(dicarbollido)cobaltate ion (1) followed by hydrolysis of the intermediates.
