The crystal structure described by Ca4CrMn3O12 is (Cubic) Perovskite-derived structured and crystallizes in the tetragonal P4/mmm space group. Ca(1) is bonded to one O(3), one O(5), two equivalent O(4), four equivalent O(1), and four equivalent O(2) atoms to form CaO12 cuboctahedra that share corners with twelve equivalent Ca(1)O12 cuboctahedra, faces with six equivalent Ca(1)O12 cuboctahedra, faces with two equivalent Cr(1)O6 octahedra, faces with two equivalent Mn(2)O6 octahedra, and faces with four equivalent Mn(1)O6 octahedra. Cr(1) is bonded to two equivalent O(3) and four equivalent O(1) atoms to form CrO6 octahedra that share corners with two equivalent Cr(1)O6 octahedra, corners with four equivalent Mn(1)O6 octahedra, and faces with eight equivalent Ca(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form MnO6 octahedra that share corners with two equivalent Cr(1)O6 octahedra, corners with two equivalent Mn(1)O6 octahedra, corners with two equivalent Mn(2)O6 octahedra, and faces with eight equivalent Ca(1)O12 cuboctahedra.

The corner-sharing octahedra are not tilted. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to four equivalent Ca(1), one Cr(1), and one Mn(1) atom. In the second O site, O(2) is bonded in a distorted linear geometry to four equivalent Ca(1), one Mn(1), and one Mn(2) atom. In the third O site, O(3) is bonded to four equivalent Ca(1) and two equivalent Cr(1) atoms to form distorted OCa4Cr2 octahedra that share corners with two equivalent O(3)Ca4Cr2 octahedra and corners with four equivalent O(5)Ca4Mn2 octahedra. The corner-sharing octahedra are not tilted. In the fourth O site, O(4) is bonded in a distorted linear geometry to four equivalent Ca(1) and two equivalent Mn(1) atoms.
