Comments:

NPD
Positional structure of non-magnetic atoms (except for the unit cell parameters) from a measurement at 45K. This reported 45K nuclear structure has been transformed to an equivalent different description, to be consistent with the different Wyckoff position considered for the Co site in the report of the magnetic structure with only the magnetic atoms.
Some H positions absent in the 45K structure

Comments (symmetry):

1k magnetic structure
2-dim irrep along special direction as SINGLE primary irrep
1-dim irrep possible as secondary, and present in the model
