The structure of tribarium dimanganese octaoxide, Ba 3Mn 2O 8, has been refined from neutron powder diffraction data, establishing that the phase is hexagonal in space group R3̄m, with unit-cell dimensions a = 5.71 and c = 21.44 Å. Two distinct Ba sites are observed, and the Mn is present in a slightly distorted tetrahedral environment.
