 Title    Triferrocenylborane -Molecular Structure in Solution and in the Solid State  
 Abstract    According to a single crystal X-ray structure determination all three ferrocenyl substituents of triferrocenylborane (1) adopt the same orientation with respect to the BC3-plane [P 2 Jc\ monoclinic; Z = 4; a = 1353.5(3), b = 1695.6(3), c = 1056.4(2) pm, ß = 109.27(3)°]. The simu­ lated X-ray powder pattern of the single crystal is identical with the powder diagram o f a macroscopic sample, indicating the presence of a single diastereomer (l a) in the solid state. How ever, at low temperature (< -9 5 °C) in solution, the 13C NM R spectra suggest the pres­ ence of the second diastereomer (lb) in which one ferrocenyl group is oriented opposite to the other two with respect to the central BC3-plane.
