The structure described by SrEu(CoO3)2 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Pm-3m space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded to four equivalent O(2) and eight equivalent O(1) atoms to form SrO12 cuboctahedra that share corners with four equivalent Eu(2)O12 cuboctahedra, corners with eight equivalent Sr(1)O12 cuboctahedra, faces with two equivalent Sr(2)O12 cuboctahedra, faces with four equivalent Eu(1)O12 cuboctahedra, and faces with eight equivalent Co(1)O6 octahedra. In the second Sr site, Sr(2) is bonded to twelve equivalent O(1) atoms to form SrO12 cuboctahedra that share corners with twelve equivalent Eu(1)O12 cuboctahedra, faces with six equivalent Sr(1)O12 cuboctahedra, and faces with eight equivalent Co(1)O6 octahedra. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded to four equivalent O(1) and eight equivalent O(2) atoms to form EuO12 cuboctahedra that share corners with four equivalent Sr(2)O12 cuboctahedra, corners with eight equivalent Eu(1)O12 cuboctahedra, faces with two equivalent Eu(2)O12 cuboctahedra, faces with four equivalent Sr(1)O12 cuboctahedra, and faces with eight equivalent Co(1)O6 octahedra. In the second Eu site, Eu(2) is bonded to twelve equivalent O(2) atoms to form EuO12 cuboctahedra that share corners with twelve equivalent Sr(1)O12 cuboctahedra, faces with six equivalent Eu(1)O12 cuboctahedra, and faces with eight equivalent Co(1)O6 octahedra. Co(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form CoO6 octahedra that share corners with six equivalent Co(1)O6 octahedra,  a faceface with one Sr(2)O12 cuboctahedra,  a faceface with one Eu(2)O12 cuboctahedra, faces with three equivalent Sr(1)O12 cuboctahedra, and faces with three equivalent Eu(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 1°. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Sr(2), two equivalent Sr(1), one Eu(1), and two equivalent Co(1) atoms to form distorted OSr3EuCo2 octahedra that share corners with ten equivalent O(2)SrEu3Co2 octahedra, corners with twelve equivalent O(1)Sr3EuCo2 octahedra, edges with four equivalent O(1)Sr3EuCo2 octahedra, faces with four equivalent O(1)Sr3EuCo2 octahedra, and faces with four equivalent O(2)SrEu3Co2 octahedra. The corner-sharing octahedral tilt angles range from 0-60°. In the second O site, O(2) is bonded to one Sr(1), one Eu(2), two equivalent Eu(1), and two equivalent Co(1) atoms to form distorted OSrEu3Co2 octahedra that share corners with ten equivalent O(1)Sr3EuCo2 octahedra, corners with twelve equivalent O(2)SrEu3Co2 octahedra, edges with four equivalent O(2)SrEu3Co2 octahedra, faces with four equivalent O(1)Sr3EuCo2 octahedra, and faces with four equivalent O(2)SrEu3Co2 octahedra.
