Graphical abstract
The high temperature crystal structure of Ba2154SmMoO6 evidencing a transverse oxygen vibration.
Highlights
► A high temperature neutron diffraction study has been performed on an isotopically enriched sample of Ba2154SmMoO6. ► A cubic–tetragonal phase transition occurs below 423 K. ► The thermal displacement parameters of the bridging oxygens are modelled anisotropically. ► There is a transverse vibration of the bridging oxygen.
