Dear:
I have a question about symmetry relationship between two space groups.
In the literature, there is a compound AB4C2. It was refined with
I-4c2 space group and A, B, and C are at 4d, 16i and 8e sites,
respectively. I got a new compound AB4D2 which can be refined very
well with high symmetry space group, I4/mcm. In my compound A, B, and
D are 4a, 16l, and 8h sites, respectively. If I draw both
structures, they look same, except some bond distances change.
The high symmetry space group is central symmetry and the another one
in non-central symmetry, but both have very similar Wyck positions.
How do I figure out the symmetry relationship between these two structures?
Your help is highly appreciated!
Thank you for your time!
Best Regards!
