1，12-十二烷二铵（C（12）DA（2+））包埋在瓜环[8]中的X-射线晶体结构表明，C（12）DA（2+）具有非常规的U型构象，这归因于良好的主-客体相互作用，克服了两个铵基的电荷-电荷排斥和高的内应力。
The X-ray crystal structure of 1,12-dodecane diammonium (C(12)DA(2+)) encapsulated in cucurbit[8]uril reveals an unconventional U-shaped conformation of C(12)DA(2+), which is attributed to the favorable host-guest interactions to overcome the charge-charge repulsion of the two ammonium groups in close proximity and high internal strain.
