摘要：

It is confirmed that AgSbO3 has a pyrochlore related structure without being hydrated. Furthermore, attempts to prepare Ag2Sb2O5(OH)2 or Ag2Sb2O5F2 were unsuccessful. It is concluded that the occurrence of the pyrochlore structure instead of the perovskite structure for certain ABO3 compounds is the result of very strong covalent bonding which tends to restrict oxygen to a maximum coordination number of four. © 1969.
