Materials Data on SrBr2O by Materials Project
SrOBr2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Sr is bonded in a distorted bent 150 degrees geometry to two equivalent O and seven Br atoms. Both Sr–O bond lengths are 2.52 Å. There are a spread of Sr–Br bond distances ranging from 3.21–3.35 Å. O is bonded in a distorted bent 150 degrees geometry to two equivalent Sr and two Br atoms. There are one shorter (2.53 Å) and one longer (2.60 Å) O–Br bond lengths. There are two inequivalent Br sites. In the first Br site, Br is bonded in a 4-coordinate geometry to three equivalent Sr and one O atom. In the second Br site, Br is bonded in a 5-coordinate geometry to four equivalent Sr and one O atom.
