Platon’s Addsym - finding extra symmetry in inorganics and minerals - P1 triclinic starting structure.
Unpublished Mineral Example
- Default Addsym gives C2/C
Tighten the addsym values:
- calc ADDSYM SHELX 1 0.2 0.4 0.2
- addsym gives P 2/c and exact fit on Pc
Update new refinement in triclinic:
- Lower R factor in Shelx
- Addsym now finds P21/c in default mode
- Thus need to be careful!
