各位大神,求助有机小分子的结构已经解析,无序不会处理,求帮助。

R factors >20% always point to serious problems (see Fo/Fc differences in the attached screenshhot).

In your case many parts of the structure are disordered (including the cation; see the screenshot). Your disorder model still does not fit with the experimental data. I suggest that a better crystal should be measured at very low temperatures.
