Reaction of (η5-C5H5)BeCl with KB5H8 results in formation of the title compound, which forms crystals in the monoclinic space group P21/c with a = 10.266 (8) A?, b = 5.616 (4) A?, c = 16.187 (7) A?, β = 98.50 (5)°, V = 923.0 (5) A?3, and Z = 4. The low-temperature X-ray structure was solved by direct methods, using anisotropic refinement of positional and temperature factors for nonhydrogen atoms and isotropic refinement for hydrogen atoms, which converged to R1 = 0.0551 and R2 = 0.0831 for 1294 independent observed reflections. The structure of [μ-(η5-C5H5)Be]B5H 8 is like that of B5H9, but with a bridge hydrogen replaced by the (η-C5H5)Be moiety. Selected chemical properties of the title compound are described.
