A N\\'{e}el transition at $T_{\\mathrm N} \\approx$ 112~K and a possible spin re-orientation transition at $T_{\\mathrm {SR}} \\approx$ 55~K are observed in the magnetization data. From neutron powder diffraction data, the nuclear structure at and below 300~K was refined in polar $P6_3cm$ space group.
