Abstract
The new diffraction patterns of the low- and high-temperature phases of Li0 .87Hf2.032(PO4)(3) and LiSn2(PO4)(3) are given and indexed on the basis of a structure refinement from neutron powder data using Rietveld method. The two isotypic compounds present a reversible phase transition: triclinic (LT , space group P (1) over bar) reversible arrow rhombohedral (HT, space grou p R (3) over bar c) which proceeds by topotactic distortion of the structur al skeleton.
