Local C2v symmetry was assumed for the NO3 group.
The temperature of the measurements was 423(10) K.

) Estimated standard errors.
) Torsional angle of the NO3 group around the Zr…N axis,
τ = 0° when the O(b)…O(b) direction is parallel to the C4 axis.
c
) Dihedral angle between the O(b)ZrO(b) and O(b)NO(b) planes.
