EuO2Br crystallizes in the monoclinic P2_1/m space group. Eu(1) is bonded in a 6-coordinate geometry to three equivalent O(1), three equivalent O(2), and three equivalent Br(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal non-coplanar geometry to three equivalent Eu(1) atoms. In the second O site, O(2) is bonded in a trigonal non-coplanar geometry to three equivalent Eu(1) atoms. Br(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Eu(1) atoms.
EuO2Br crystallizes in the monoclinic P2_1/m space group. Eu(1) is bonded in a 6-coordinate geometry to three equivalent O(1), three equivalent O(2), and three equivalent Br(1) atoms. There are two shorter (2.31 Å) and one longer (2.39 Å) Eu(1)-O(1) bond length. There is one shorter (2.32 Å) and two longer (2.34 Å) Eu(1)-O(2) bond lengths.
