C15H20B9Co, Mr = 356.55, orthorhombic, P212121, a = 8.759 (3), b = 13.037 (3), c = 15.366 (4) A, V= 1754.7 (8)Å3, Z = 4, D x = 1.349 Mg m-3, Mo Kα, ,λ = 0.71069 Å μ = 0.94 mm-1, F(000) = 728, T = 291 (1) K, R = 0.0793 for 1930 independent observed reflections. The (staggered) conformation of the fluorenyl ligand relative to the metal-bonded C2B 3 face of the carbaborane is such that one pair of junction C atoms is trans to a B-B connectivity, the other being trans to a B-C connectivity. This conformation is shown to be the optimum by analysis of the results from molecular orbital calculations on a model compound.
