The room temperature distortion of LiZr2(PO4)(3) reacted at 1100 degrees C and above, widely considered to be monoclinic, is proved here to be triclinic by detailed indexing of its powder X-ray diffraction pattern taken under good resolution conditions. This and other results seem to indicate that the law temperature distortion of most LiMe2IV(PO4)(3) rhombohedral NASICON-type structures, is triclinic, while the homologous Na compounds are known to be monoclinic.
