The structure of the n ¼ 4 Aurivillius oxide BaBi 4 Ti 4 O 15 has been studied at room temperature using powder neutron diffraction, and from 300 to 1000 K using synchrotron X-ray diffraction methods. The structure is orthorhombic (space group A2 1 am) at 300 K and transforms to a tetragonal (I4/mmm
