Non-conservative APB [(001)\ {{1}\over{4}}[10{\overline 1}]] as shown schematically in Fig. 3[link](c) with the anion and cation positions projected on the plane (010). The y values of the atomic positions are given in multiples of [{{1}\over{8}}a]. The bidirectional arrows mark the face-sharing tetrahedral and octahedral cations at the APB.
