文摘

The anionic nitriles 1-R-12-NC–CB₁₁H₁₀^– (R = H, CH₃, I, COOH), 12-NC-1-H–CB₁₁Me₁₀^–, and 12-NC-1-H–CB₁₁F₁₀^– were prepared, and three of them were examined for complex formation with (Et₃P)₂Pt(II) and (Et₃P)₂Pd(II). Several stable internally charge-compensated zwitterionic complexes were obtained and characterized. RI-BP86/SV(P) calculations suggest that their dipole moments exceed 20 D. An attempt to measure the dipole moments in solution failed due to insufficient solubility in solvents of low polarity.
