2-dim irrep as primary. Although this irrep alone for a general direction can result in the observed MSG, the reported direction of the moments on the basal plane is along a special direction which keeps a higher monoclinic C2'/m symmetry. Not clear how in this case the direction on the xy plane, which usually remains undetermined when analyzing powder data could in this case be fully determined. The reduction to triclinic P-1' is due to the z-component of the Mn moments, which corresponds the 1-dim irrep mGM1-, which must then be taken as a second primary irrep.
The zero moment at the Yb site is symmetry-forced.
