The molecular polarities of compounds 1,2-C2B10H11NC and 1,2-C2B10H11CH2NC were less than that of the 1,2-C2B10H12, indicating that there is disadvantage for these isonitrile derivatives used in boron neutron capture therapy.

• 1；2-C2B10H11NC和1；2-C2B10H11CH2NC的分子极性均比1；2-C2B10H12的弱；这不利于它们在硼中子捕获疗法中的应用.
