SrCaEuSbO6 is Orthorhombic Perovskite-derived structured and crystallizes in the orthorhombic Pnnn space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a distorted body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. In the second Sr site, Sr(2) is bonded in a distorted square co-planar geometry to four equivalent O(1) and four equivalent O(3) atoms. There are two inequivalent Ca sites. In the first Ca site, Ca(1) is bonded in a square co-planar geometry to four equivalent O(3) atoms. In the second Ca site, Ca(2) is bonded to four equivalent O(1), four equivalent O(2), and four equivalent O(3) atoms to form CaO12 cuboctahedra that share faces with four equivalent Eu(1)O6 octahedra and faces with four equivalent Sb(1)O6 octahedra. Eu(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form EuO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra and faces with two equivalent Ca(2)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 25-29°. Sb(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form SbO6 octahedra that share corners with six equivalent Eu(1)O6 octahedra and faces with two equivalent Ca(2)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 25-29°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to one Sr(1), one Sr(2), one Ca(2), one Eu(1), and one Sb(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Sr(1), one Ca(2), one Eu(1), and one Sb(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Sr(2), one Ca(1), one Ca(2), one Eu(1), and one Sb(1) atom.
