The Syntheses and Crystal Structures of some Ten-vertex (MCB8; M=Ru or Os) Metallacarbaboranes: 9,9,9-(CO)(PPh3)2-nido-9,6-MCB8H10-5-(PPh3)> (M=Ru or Os) and <9,9,9-(eta-C5H5)(H)(PPh3)-arachno-9,6-RuCB8H12>

The reaction of M=Ru or Os) with arachno-(1-) yields the nido-metalllacarbaboranes <9,9,9-(CO)(PPh3)2-9,6-MCB8H10-5-(PPh3)> in reasonable yields as red and orange crystals respectively.A phosphine ligand is transferred from the metal atom to the cage in each case, and they both show a decarborane(14)-like cage structure with the 6- and 9-positions occupied by CH and M(CO)(PPh3)2 fragments respectively, as confirmed by single-crystal X-ray diffraction analysis.Compounds (1) and (2) are isostructural and isomorphous with their crystals are monoclinic, space group P21/n, with Z=4.R=0.087 for 2 670 observed =3.0> reflections for (1) and 0.050 for 3525 observed reflections for (2) respectively.A similar reaction with yields the arachno species <9,9,9-(eta-C5H5)(H)(PPh3)-9,6-RuCB8H12>, (3).In this case the cage arrangement as determined by a sigle-crystal X-ray diffraction study, is similar to that in (2-) with 6- and 9-positions substituted by CH2 and RuH(eta-C5H5)(PPh3) fragments, respectively.The crystals are monoclinic, space group P21/n, with Z=4, R=0.046 for 3 523 observed reflections.The application of the skeletal electron counting rules to this arachno structure is discussed.
