The compound described by EuO3 crystallizes in the orthorhombic Pmc2_1 space group. Eu(1) is bonded in a 9-coordinate geometry to two equivalent O(2), three equivalent O(1), and four equivalent O(3) atoms. There are three 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 O(2) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Eu(1) and two equivalent O(1) atoms. In the third O site, O(3) is bonded in a square co-planar geometry to four equivalent Eu(1) atoms. is represented by the CIF file [CIF]
