摘要：

The meta-antimonates, MSb2O6, M = Ca, Sr and Ba, have been prepared, and their crystal structures refined from powder X-ray diffraction data. The interatomic distances have been determined to reasonable accuracy and the preferred space group was found to be P31mBAR, not the previously identified P312 (a subgroup of P31mBAR). These and other isomorphous AB2X6 materials are now identified as belonging to the Li2ZrF6 (or better, PbSb2O6) structure type. Powder diffraction data in the JCPDS-PDF format are presented.
