摘要：

Neutron and X-ray powder diffractograms of the title compound were refined by the Rietveld method. Within the bismuth layer an additional oxygen site with population parameter 0.12 was found which is interpreted as the excess oxygen. From the comparison of population parameters from neutron and X-ray data we conclude that Pb at least partially goes to the Ca position. The incommensurate modulation of the structure is reflected by the anisotropy of temperature factors. © 1990.
