removed under vacuum or in the presence of molecular sieves, B(C(6)Cl(5))(3) (6) is completely stable to refluxing toluene/H(2)O for several days. Compounds3, 5, and 6 have been structurally characterized using single crystal X-ray diffraction and represent the first structuredeterminations for compounds featuring B-C(6)Cl(5) bonds; each exhibits a trigonal planar geometry about B, despite having different

and ClB(C6Cl5)2 and is a violet–blue species featuring an extremely electron deficient Fe(II) centre (E1/2 = +550 mV with respect to ferrocene/ferrocenium). A combination of structural, spectroscopic and reactivity studies of these and related ferrocenylboranes allow some general comments to be made concerning the relative steric and electronic properties of the C6Cl5 group. Thus, in terms of their
