Materials Data on EuBrO2 by Materials Project

EuO2Br crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Eu is bonded in a 6-coordinate geometry to six O and three equivalent Br atoms. There are a spread of Eu–O bond distances ranging from 2.31–2.39 Å. There are one shorter (3.30 Å) and two longer (3.32 Å) Eu–Br bond lengths. There are two inequivalent O sites. In the first O site, O is bonded in a trigonal non-coplanar geometry to three equivalent Eu atoms. In the second O site, O is bonded in a trigonal non-coplanar geometry to three equivalent Eu atoms. Br is bonded in a distorted trigonal non-coplanar geometry to three equivalent Eu atoms.
