摘要: The crystal structure of the compound Pb12Ta9O20F29 has been determined from single X-ray data. symmetry is tetragonal (space group I4/m) with unit cell dimensions a = 22.8951(6) A and c 3.9202(2) A. contains columns ReO3 type, 3 × octahedra wide, separated by “Pb2F2+2” layers. It thus related to structures layered Bi2O2+2 perovskites, so-called Aurivillius phases. Most fluorine atoms in have located means bond strength calculations.
