摘要：
The structure of PbBaYSrCu3O7 has been determined by neutron and X-ray powder diffraction using a profile analysis method. The symmetry is tetragonal with space group I4mm and cell parameters a = 3.8436(1) Å and c = 27.426(1) Å. The structure of this oxide is built up from the intergrowth of single rock salt layers with triple perovskite layers. The perovskite layer is oxygen deficient and perfectly ordered according to a sequence of one layer of Cu1O2 sticks and two layers of CuO5 pyramids. The ordering of copper and lead on two different sites is demonstrated, showing definitively the existence of a perfectly ordered "0223" type structure, contrary to the existence of mixed lead/copper layers proposed by previous authors. The oxygen distribution and coordination of lead and copper are compared to those observed for Pb2Sr2YCu3O8 and PbBa0.8Sr1.2PrCeCu3O9. © 1992.
