The material described by La4Cu3SeO12 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Im-3m space group. La(1) is bonded to six equivalent O(1) and six equivalent O(2) atoms to form LaO12 cuboctahedra that share corners with twelve equivalent La(1)O12 cuboctahedra, faces with six equivalent La(1)O12 cuboctahedra, faces with two equivalent Se(1)O6 octahedra, and faces with six equivalent Cu(1)O6 octahedra. Cu(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CuO6 octahedra that share corners with two equivalent Se(1)O6 octahedra, corners with four equivalent Cu(1)O6 octahedra, and faces with eight equivalent La(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Se(1) is bonded to six equivalent O(2) atoms to form SeO6 octahedra that share corners with six equivalent Cu(1)O6 octahedra and faces with eight equivalent La(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent La(1) and two equivalent Cu(1) atoms to form distorted OLa4Cu2 octahedra that share corners with eight equivalent O(2)La4CuSe octahedra, corners with fourteen equivalent O(1)La4Cu2 octahedra, edges with four equivalent O(2)La4CuSe octahedra, faces with four equivalent O(1)La4Cu2 octahedra, and faces with four equivalent O(2)La4CuSe octahedra. The corner-sharing octahedral tilt angles range from 0-62°. In the second O site, O(2) is bonded to four equivalent La(1), one Cu(1), and one Se(1) atom to form distorted OLa4CuSe octahedra that share corners with eight equivalent O(1)La4Cu2 octahedra, corners with fourteen equivalent O(2)La4CuSe octahedra, edges with four equivalent O(1)La4Cu2 octahedra, faces with four equivalent O(1)La4Cu2 octahedra, and faces with four equivalent O(2)La4CuSe octahedra. The corner-sharing octahedral tilt angles range from 0-62°. is represented by the CIF card [CIF]
