NaO2Br crystallizes in the monoclinic P2_1/c space group. Na(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form a mixture of distorted corner and edge-sharing NaO4 trigonal pyramids. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to two equivalent Na(1) and one Br(1) atom. In the second O site, O(2) is bonded in a distorted T-shaped geometry to two equivalent Na(1) and one Br(1) atom. Br(1) is bonded in a water-like geometry to one O(1) and one O(2) atom.
NaO2Br crystallizes in the monoclinic P2_1/c space group. Na(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form a mixture of distorted corner and edge-sharing NaO4 trigonal pyramids. There is one shorter (2.29 Å) and one longer (2.36 Å) Na(1)-O(1) bond length. There is one shorter (2.29 Å) and one longer (2.46 Å) Na(1)-O(2) bond length. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to two equivalent Na(1) and one Br(1) atom. The O(1)-Br(1) bond length is 1.76 Å. In the second O site, O(2) is bonded in a distorted T-shaped geometry to two equivalent Na(1) and one Br(1) atom. The O(2)-Br(1) bond length is 1.74 Å. Br(1) is bonded in a water-like geometry to one O(1) and one O(2) atom.
