The salt [Na][Pt(PEt3)2(η5-7-CB10H 11)] (1a) has been prepared. Protonation affords the hydrido complex [PtH(PEt3)2(η5-7-CB10H 11)] (2) while reactions with [AuCl(PPh3)], [CuCl(PPh3)]4, and [HgClPh] yield the dimetal compounds [PtM(PEt3)2(PPh3)(η5-7-CB 10H11)] (3a, M = Au; 3b, M = Cu) and [PtHgPh(PEt3)2(η5-7-CB10H 11)] (3c), respectively. The salt [N(PPh3)2][Pt(CO)(PPh3)(η 5-7-CB,oHn)] (4) has also been obtained. Single-crystal X-ray diffraction studies have been made on 2 and 3a-c. Complexes 2, 3a, and 3c have similar molecular structures with H, Au(PPh3), and HgPh groups, respectively, σ-bonded to the Pt of the Pt(PEt3)2(η5-7-CB10H 11) group. In 3b, however, the copper atom of the Cu(PPh3) moiety is attached to the Pt(PEt3)2(η5-7-CB10H 11) fragment both by a Pt-Cu σ-bond and by two exopolyhedral B-HCu donor bonds from BH groups in the open face of the nido-7-CB10H11 cage ligating the platinum. The structure of the salt 4 has also been determined by X-ray diffraction.
