The structure described by KEu(SnO3)2 is Orthorhombic Perovskite-derived structured and crystallizes in the orthorhombic Pmn2_1 space group. K(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), two equivalent O(4), and four equivalent O(3) atoms. Eu(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), two equivalent O(3), and four equivalent O(4) atoms. Sn(1) is bonded to one O(1), one O(2), two equivalent O(3), and two equivalent O(4) atoms to form corner-sharing SnO6 octahedra. The corner-sharing octahedral tilt angles range from 18-34°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one K(1), one Eu(1), and two equivalent Sn(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to one K(1), one Eu(1), and two equivalent Sn(1) atoms. In the third O site, O(3) is bonded in a 5-coordinate geometry to two equivalent K(1), one Eu(1), and two equivalent Sn(1) atoms. In the fourth O site, O(4) is bonded in a 5-coordinate geometry to one K(1), two equivalent Eu(1), and two equivalent Sn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
