Comaring with the neutral states, the bondlengths and the inter ring twist angles of the charged states are changed obviously.
与中性态相比，带电态下其分子结构表现在C - C键的键长及环与环间的扭转角发生显著的改变。

Obvious changes of atomic natural charge happened to atoms C(1), H(11), O(28), O(29) and N(27). The bondlengths and bond angles related to these atoms were also varied greatly.
The variation of coordination bondlengths in the complex compounds of yttrium due to the balance between Van der Waals and coordination bond energies are given.
