( No. 221) with the O/N anions completely disordered in the anion octahedra (Kim et al., 2004; Pors et al., 1988; Fig. 1). The situation of SrTaO2N is more complex, and several structural models have been reported: I4/mcm (No. 140; Gu nther et al., 2000; Zhang et al., 2011; Kim et al., 2004; Clarke et al., 2002), I112/m (No. 12; Yang et al., 2011) and Fmmm (No. 69; Clark et al., 2013).

A further Ta- O/N octahedra displacement [R 5 - (a,0,0), rotation about the c axis] distortion was observed in SrTaO2N. This distortion mode is accompanied by an increased unit-cell distortion that decreases as the temperature increases. Ultimately a second-order phase transition caused by the loss of the R 5 - (a,0,0) mode was observed at 400- 450 K.
