Positional structure including cell parameters is missing. Here that of a measurement at 173K reported in 2011 is used.
Eu moment direction on the ab plane is undetermined. A direction of maximal symmetry has been chosen arbitrarily. 
The other distinct moment direction of maximal symmetry with a different MSG is (2,1,0) (or equivalent), with MSG C_c2/c(15.90) with transformation to standard: 2a+b,b,2c;0,0,0.
