Powder neutron diffraction of \(\mathrm{Ca}_{0.8} \mathrm{Bi}_{1.2} \mathrm{O}_{2.6}\) at \(8 \mathrm{~K}\) reveals a pseudocubic order-disorder structure, space group \(R 3 m, a=\) \(424.6 \mathrm{pm}\) and \(\alpha=90^{\circ}\). The average structure is of anti- \(\alpha-\mathrm{AgI}\) type, space
