A fully asymmetric structure of the [4,8'-μ-R2N-commo-(1,2-C2B9H10)2-3-Co] (R = H and Me) cobaltacarborane complexes with a monoatomic nitrogen bridge between both ligands was determined by high resolution mass spectrometry and 1H, 11B NMR, [11B-11B] COSY NMR spectroscopy. Their structures have been also supported by the resolution of both compounds into enantiomers on the β-cyclodextrin HPLC column. A complex reaction of the [3-Co-commo-(1,2-C2B9H11)2]- ion with the NO+ cation is briefly discussed and the tentative structure of the second main product is also suggested.
