The crystal structure described by SrGd(CoO3)2 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Sr(1) is bonded to twelve equivalent O(1) atoms to form SrO12 cuboctahedra that share corners with twelve equivalent Sr(1)O12 cuboctahedra, faces with six equivalent Gd(1)O12 cuboctahedra, and faces with eight equivalent Co(1)O6 octahedra. Gd(1) is bonded to twelve equivalent O(1) atoms to form GdO12 cuboctahedra that share corners with twelve equivalent Gd(1)O12 cuboctahedra, faces with six equivalent Sr(1)O12 cuboctahedra, and faces with eight equivalent Co(1)O6 octahedra. Co(1) is bonded to six equivalent O(1) atoms to form CoO6 octahedra that share corners with six equivalent Co(1)O6 octahedra, faces with four equivalent Sr(1)O12 cuboctahedra, and faces with four equivalent Gd(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded to two equivalent Sr(1), two equivalent Gd(1), and two equivalent Co(1) atoms to form a mixture of distorted corner, edge, and face-sharing OSr2Gd2Co2 octahedra. The corner-sharing octahedral tilt angles range from 0-60°. is represented by the CIF file [CIF]
