Sr2TiMnO6 is (Cubic) Perovskite-derived structured and crystallizes in the tetragonal I4/m space group. Sr(1) is bonded to four equivalent O(1) and eight equivalent O(2) atoms to form SrO12 cuboctahedra that share corners with twelve equivalent Sr(1)O12 cuboctahedra, faces with six equivalent Sr(1)O12 cuboctahedra, faces with four equivalent Ti(1)O6 octahedra, and faces with four equivalent Mn(1)O6 octahedra. Ti(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form TiO6 octahedra that share corners with six equivalent Mn(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-3°. Mn(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form MnO6 octahedra that share corners with six equivalent Ti(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-3°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to four equivalent Sr(1), one Ti(1), and one Mn(1) atom. In the second O site, O(2) is bonded in a distorted linear geometry to four equivalent Sr(1), one Ti(1), and one Mn(1) atom.
