Materials Data on EuBr2O by Materials Project
EuOBr2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Eu is bonded in a 2-coordinate geometry to two equivalent O and seven Br atoms. Both Eu–O bond lengths are 2.25 Å. There are a spread of Eu–Br bond distances ranging from 3.09–3.40 Å. O is bonded in a bent 120 degrees geometry to two equivalent Eu atoms. There are two inequivalent Br sites. In the first Br site, Br is bonded to four equivalent Eu atoms to form a mixture of distorted edge and corner-sharing BrEu4 tetrahedra. In the second Br site, Br is bonded in a trigonal non-coplanar geometry to three equivalent Eu atoms.
