SrO2 crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded in a distorted q4 geometry to ten equivalent O(1) atoms. O(1) is bonded to five equivalent Sr(1) and one O(1) atom to form a mixture of distorted corner, edge, and face-sharing OSr5O pentagonal pyramids.
SrO2 crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded in a distorted q4 geometry to ten equivalent O(1) atoms. There are two shorter (2.59 Å) and eight longer (2.62 Å) Sr(1)-O(1) bond lengths. O(1) is bonded to five equivalent Sr(1) and one O(1) atom to form a mixture of distorted corner, edge, and face-sharing OSr5O pentagonal pyramids. The O(1)-O(1) bond length is 1.50 Å.
