The material described by KEuZr4O12 crystallizes in the orthorhombic Amm2 space group. K(1) is bonded in a distorted q6 geometry to two equivalent O(3), four equivalent O(1), and four equivalent O(4) atoms. Eu(1) is bonded in a 4-coordinate geometry to two equivalent O(2), two equivalent O(3), and two equivalent O(5) atoms. Zr(1) is bonded to one O(2), one O(3), one O(4), one O(5), and two equivalent O(1) atoms to form corner-sharing ZrO6 octahedra. The corner-sharing octahedral tilt angles range from 17-45°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one K(1) and two equivalent Zr(1) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to one Eu(1) and two equivalent Zr(1) atoms. In the third O site, O(3) is bonded in a 4-coordinate geometry to one K(1), one Eu(1), and two equivalent Zr(1) atoms. In the fourth O site, O(4) is bonded in a 2-coordinate geometry to two equivalent K(1) and two equivalent Zr(1) atoms. In the fifth O site, O(5) is bonded in a distorted T-shaped geometry to one Eu(1) and two equivalent Zr(1) atoms. is represented by the CIF file [CIF]
