NPD
Positional structure from a determination at 298K
Spin orientation on the basal plane is undetermined. Here a direction of maximal symmetry is taken arbitrarily.

k-maximal symmetry
2-dim irrep along a special direction
Alternative MSGs depending on the undetermined spin orientation: along (110) direction: Cm'ma (a+b,-a+b,c;0,1/2,0) and along a general direction on the basal plane P2'/c (a,-c,-a+b;0,0,0) with the transformation to standard with respect to the parent setting.
linear magnetoelectric effect is symmetry allowed
