Dear all,Recently, I have refined the structure using powder data. In each asymmetric unit of Pmc21, there are two chemically similar but crystallographically different complexes. The center of these two complexes is rougly around 0,0,0.75. Therefore, the true space group may not be Pmc21. I am glad to know if there is a software to detect symmetry and suggest probable space group.
Thank you very much. best regards stephen
