The compound described by BaEu(SnO3)4 crystallizes in the orthorhombic Cmmm space group. Ba(1) is bonded to four equivalent O(1); four equivalent O(2); and four O(3,3) atoms to form BaO12 cuboctahedra that share corners with four equivalent Ba(1)O12 cuboctahedra, corners with eight equivalent Eu(1)O12 cuboctahedra, and faces with eight equivalent Sn(1)O6 octahedra. Eu(1) is bonded to four equivalent O(1); four equivalent O(2); and four O(4,4,4) atoms to form EuO12 cuboctahedra that share corners with four equivalent Eu(1)O12 cuboctahedra, corners with eight equivalent Ba(1)O12 cuboctahedra, and faces with eight equivalent Sn(1)O6 octahedra. Sn(1) is bonded to one O(3), one O(4), two equivalent O(1), and two equivalent O(2) atoms to form SnO6 octahedra that share corners with six equivalent Sn(1)O6 octahedra, faces with two equivalent Ba(1)O12 cuboctahedra, and faces with two equivalent Eu(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-7°. There are seven inequivalent O sites. In the first O site, O(4) is bonded in a distorted square co-planar geometry to two equivalent Eu(1) and two equivalent Sn(1) atoms. In the second O site, O(1) is bonded in a distorted square co-planar geometry to one Ba(1), one Eu(1), and two equivalent Sn(1) atoms. In the third O site, O(2) is bonded in a distorted square co-planar geometry to one Ba(1), one Eu(1), and two equivalent Sn(1) atoms. In the fourth O site, O(3) is bonded in a distorted square co-planar geometry to two equivalent Ba(1) and two equivalent Sn(1) atoms. In the fifth O site, O(4) is bonded in a distorted square co-planar geometry to two equivalent Eu(1) and two equivalent Sn(1) atoms. In the sixth O site, O(3) is bonded in a distorted square co-planar geometry to two equivalent Ba(1) and two equivalent Sn(1) atoms. In the seventh O site, O(4) is bonded in a distorted square co-planar geometry to two equivalent Eu(1) and two equivalent Sn(1) atoms. is represented by the CIF file [CIF]
