Abstract

Syntheses, properties and constitutions of eleven asymmetric cobaltacarboranes with various substituents on monoatomic bridges between both ligands of the type 6,6'-μ-R<i><sub>n</sub></i>E(1,7-C<sub>2</sub>B<sub>9</sub>H<sub>10</sub>)<sub>2</sub>-2-Co (E = O, R = methyl; E = S, R = ethyl, propyl, isopropyl, allyl, butyl, hexyl and CH<sub>3</sub>OCOCH<sub>2</sub>; E = N, R = H (H), methyl, (H), and dimethyl) are described. Constitution assignation of all compounds are based on <sup>1</sup>H and <sup>11</sup>B NMR spectroscopy experiments complemented by <sup>11</sup>B-<sup>11</sup>B COSY NMR and mass spectrometry; UV-VIS, melting points and TLC parameters are also presented. Only the racemic forms were obtained, although in principle, the <i>meso</i>-forms might result as well.
