Materials Data on SrTi4(CuO4)3 by Materials Project
SrCu3Ti4O12 crystallizes in the cubic Im-3 space group. The structure is three-dimensional. Sr2+ is bonded to twelve equivalent O2- atoms to form SrO12 cuboctahedra that share faces with eight equivalent TiO6 octahedra. All Sr–O bond lengths are 2.65 Å. Ti4+ is bonded to six equivalent O2- atoms to form TiO6 octahedra that share corners with six equivalent TiO6 octahedra and faces with two equivalent SrO12 cuboctahedra. The corner-sharing octahedral tilt angles are 39°. All Ti–O bond lengths are 1.99 Å. Cu2+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Cu–O bond lengths are 1.99 Å. O2- is bonded in a 3-coordinate geometry to one Sr2+, two equivalent Ti4+, and one Cu2+ atom.
