The material described by CaEuV2O6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Pm-3m space group. There are two inequivalent Ca sites. In the first Ca site, Ca(1) is bonded to four equivalent O(1) and eight equivalent O(2) atoms to form CaO12 cuboctahedra that share corners with four equivalent Eu(2)O12 cuboctahedra, corners with eight equivalent Ca(1)O12 cuboctahedra, faces with two equivalent Ca(2)O12 cuboctahedra, faces with four equivalent Eu(1)O12 cuboctahedra, and faces with eight equivalent V(1)O6 octahedra. In the second Ca site, Ca(2) is bonded to twelve equivalent O(2) atoms to form CaO12 cuboctahedra that share corners with twelve equivalent Eu(1)O12 cuboctahedra, faces with six equivalent Ca(1)O12 cuboctahedra, and faces with eight equivalent V(1)O6 octahedra. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded to four equivalent O(2) and eight equivalent O(1) atoms to form EuO12 cuboctahedra that share corners with four equivalent Ca(2)O12 cuboctahedra, corners with eight equivalent Eu(1)O12 cuboctahedra, faces with two equivalent Eu(2)O12 cuboctahedra, faces with four equivalent Ca(1)O12 cuboctahedra, and faces with eight equivalent V(1)O6 octahedra. In the second Eu site, Eu(2) is bonded to twelve equivalent O(1) atoms to form EuO12 cuboctahedra that share corners with twelve equivalent Ca(1)O12 cuboctahedra, faces with six equivalent Eu(1)O12 cuboctahedra, and faces with eight equivalent V(1)O6 octahedra. V(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form VO6 octahedra that share corners with six equivalent V(1)O6 octahedra,  a faceface with one Ca(2)O12 cuboctahedra,  a faceface with one Eu(2)O12 cuboctahedra, faces with three equivalent Ca(1)O12 cuboctahedra, and faces with three equivalent Eu(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 1-2°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to one Ca(1), one Eu(2), two equivalent Eu(1), and two equivalent V(1) atoms. In the second O site, O(2) is bonded in a distorted linear geometry to one Ca(2), two equivalent Ca(1), one Eu(1), and two equivalent V(1) atoms. is represented by the CIF file [CIF]
