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.
制备了阴离子腈1-R-12-NC-CB11H10(-)（R = H、CH3、I、COOH）、12-NC-1-H-CB11Me10(-)和12-NC-1-H-CB11F10(-)，并对其中三种与(Et3P)2Pt(II)和(Et3P)2Pd(II)形成配合物的情况进行了研究。获得并表征了几种稳定的内部电荷补偿两性离子配合物。RI-BP86/SV(P)计算表明它们的偶极矩超过20 D。由于在低极性溶剂中的溶解度不足，未能成功测量溶液中的偶极矩。
