A slight orthorhombic distortion of perovskite type crystal lattice of antiferro-electric PbZr0. which is very close to tetragonal, was successfully detected bycompairing carefully the .observed and the calculated X-ray diffraction profilesof the powder diffractometry data. The prototypic cubic perovskite cell changesthe shape into monoclinic, a,.=c.=4.l58, 6.=4.ll0A and f3=9O'5.6' at roomtemperature, confirming Shata[ova et al.'s result. In contrast to the Shatalova'sresult, however, the lattice slightly contracts along the direction of antiparallelshift of Pb tons rather than the extension. The true orthorhombic unit cell isa=2a. cos (p/2), b=4a. sin (fi/2) and c=2b,..
