The crystal structure described by EuZrO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Eu(1) is bonded in a 8-coordinate geometry to two equivalent O(1) and six equivalent O(2) atoms. Zr(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing ZrO6 octahedra. The corner-sharing octahedral tilt angles range from 28-29°. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Eu(1) and two equivalent Zr(1) atoms to form distorted corner-sharing OEu2Zr2 tetrahedra. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Eu(1) and two equivalent Zr(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
