Abstract

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-H⇀Cu 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.
