Hi Ben,

When I used the wrong calib.xml to perform the minimization,I have done
your suggestion,the step by step minimization is showed that the one of
the metal ion ZN2+ have a large force to attract the furanic ring oxygen
of the ligand,then the furanic ring was moved right and left until my
ligand was deformed in that position.

Best Regards
JiYuan
