The crystal structure described by KEuMn4O12 crystallizes in the orthorhombic Amm2 space group. K(1) is bonded to two equivalent O(2), two equivalent O(3), four equivalent O(1), and four equivalent O(4) atoms to form distorted KO12 cuboctahedra that share corners with four equivalent K(1)O12 cuboctahedra, corners with eight equivalent Eu(1)O12 cuboctahedra, and faces with eight equivalent Mn(1)O6 octahedra. Eu(1) is bonded to two equivalent O(2), two equivalent O(3), four equivalent O(1), and four equivalent O(5) atoms to form distorted EuO12 cuboctahedra that share corners with four equivalent Eu(1)O12 cuboctahedra, corners with eight equivalent K(1)O12 cuboctahedra, and faces with eight equivalent Mn(1)O6 octahedra. Mn(1) is bonded to one O(2), one O(3), one O(4), one O(5), and two equivalent O(1) atoms to form MnO6 octahedra that share corners with six equivalent Mn(1)O6 octahedra, faces with two equivalent K(1)O12 cuboctahedra, and faces with two equivalent Eu(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 11-19°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one K(1), one Eu(1), and two equivalent Mn(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to one K(1), one Eu(1), and two equivalent Mn(1) atoms. In the third O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to one K(1), one Eu(1), and two equivalent Mn(1) atoms. In the fourth O site, O(4) is bonded in a 2-coordinate geometry to two equivalent K(1) and two equivalent Mn(1) atoms. In the fifth O site, O(5) is bonded in a 2-coordinate geometry to two equivalent Eu(1) and two equivalent Mn(1) atoms. is represented by the CIF card [CIF]
