AB  - The existing controversies about the space group symmetries of Pb(Zr<sub>x</sub>Ti<sub>1−x</sub>)O<sub>3</sub> (PZT) above and below the antiferrodistortive (AFD) phase-transition temperature (T<sub>AFD</sub>) in the Zr<sup>4+</sup>-rich (0.620 ≲ x ≲ 0.940) compositions are addressed using the results of dielectric, synchrotron x-ray powder diffraction (SXRPD) and neutron powder diffraction (NPD) studies. These compositions undergo an AFD phase transition above room temperature due to tilting of oxygen octahedra leading to a superlattice phase of PZT. We have substituted 6
