Abstract
A revised structure for the [6,9-C2B8H10]2- anion is siggested on the basis of its NMR spectra. The anion reacts with the [cis-PtL2CL2] (L = P(C6H5)3, S(C2H5)2) and [Ni(cis-1,2-DACH)..Cl2] (DACH = diaminocyclohexane) complexes to produce a family of suare-planar [μ-6,9-ML2-6,9-C2B8H10] (M = Pt, Ni) nido-metalladicarbaboranes containing an unusual metallic bridge linking both skeletal carbon atoms of the carborane ligand. The structure of the complexes is proposed on the basis of their NMR spectra and an X-ray diffraction study.
