The structure described by SrO3 crystallizes in the orthorhombic Pmc2_1 space group. Sr(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 3-coordinate geometry to three equivalent Sr(1) and two equivalent O(2) atoms. In the second O site, O(2) is bonded in a 5-coordinate geometry to two equivalent Sr(1), one O(3), and two equivalent O(1) atoms. In the third O site, O(3) is bonded to four equivalent Sr(1) and one O(2) atom to form a mixture of distorted corner and edge-sharing OSr4O trigonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
