Abstract in another language

The crystal structure of europium strontium manganese trioxide, Eu0.6Sr0.4MnO3, has been refined using a multiply twinned single crystal containing six twin components. The MnO6 octa­hedra show Jahn-Teller distortions with nearly fourfold symmetry, but the octa­hedral tilting scheme reduces the crystal symmetry to ortho­rhom­bic (space group Pbnm). The refinement of site occupancies and the analysis of difference Fourier maps show that the Eu3+ and Sr2+ cations occupy different crystallographic positions with eightfold and twelvefold coordination, respectively.
