The material described by EuAlO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Eu(1) is bonded in a 12-coordinate geometry to four equivalent O(1) and eight equivalent O(2) atoms. Al(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing AlO6 octahedra. The corner-sharing octahedral tilt angles range from 14-16°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to four equivalent Eu(1) and two equivalent Al(1) atoms. In the second O site, O(2) is bonded in a 2-coordinate geometry to four equivalent Eu(1) and two equivalent Al(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
