The structure of completely exchanged Mn 2+ —ß″—Al 2 O 3 (Mn 0.77 Al 10.46 Mg 0.54 O 17 ) crystals has been investigated by single—crystal X—ray diffraction methods at room temperature (trigonal, R3¯, Z = 3, a = 560.65(7), c = 3329.3(9) pm). The manganese ions (Mn 2+ ) are found to occupy Beevers‐Ross (56 %) and mid—oxygen positions (44 %) in nearly the same amounts. The crystal composition was confirmed by electron probe microanalyses on various crystals.
