The structure described by EuGaO3 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(2) and six equivalent O(1) atoms. Ga(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing GaO6 octahedra. The corner-sharing octahedral tilt angles are 29°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to three equivalent Eu(1) and two equivalent Ga(1) atoms. In the second O site, O(2) is bonded to two equivalent Eu(1) and two equivalent Ga(1) atoms to form distorted corner-sharing OEu2Ga2 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
