Dear Dr.Evans, Thanks for your reply.
The unit cell parameters are a=140 , b=110, c=44., Hence i am afraid, the interchange couldn't have occurred due to similar a and b. I had performed dehydration using PEG in the said case. I agree that dehydration or soaking with ligand can hardly lead to the interchange of axis.But, what i find difficult to understand is how come only in three out of nice structures,interchange of cell axis occurs, where i had maintained similar experimental conditions for all the nine cases. Is there any logical explanation for this or am i doing something wrong? The sp group are P21212 in all the cases. Thanks in advance Regards, T.chandran
