Materials Data on SrBr2 by Materials Project

SrBr2 is Baddeleyite-like structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Sr2+ is bonded to seven Br1- atoms to form a mixture of distorted edge and corner-sharing SrBr7 pentagonal bipyramids. There are a spread of Sr–Br bond distances ranging from 3.09–3.23 Å. There are two inequivalent Br1- sites. In the first Br1- site, Br1- is bonded to four equivalent Sr2+ atoms to form a mixture of distorted edge and corner-sharing BrSr4 trigonal pyramids. In the second Br1- site, Br1- is bonded in a trigonal non-coplanar geometry to three equivalent Sr2+ atoms.

Materials Data on SrBr3 by Materials Project

SrBr3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Sr is bonded to twelve equivalent Br atoms to form a mixture of face and corner-sharing SrBr12 cuboctahedra. There are six shorter (3.38 Å) and six longer (3.55 Å) Sr–Br bond lengths. Br is bonded in a see-saw-like geometry to four equivalent Sr atoms.

Materials Data on SrBr2 by Materials Project

SrBr2 is Rutile structured and crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. Sr2+ is bonded to six equivalent Br1- atoms to form a mixture of edge and corner-sharing SrBr6 octahedra. The corner-sharing octahedral tilt angles are 50°. All Sr–Br bond lengths are 3.08 Å. Br1- is bonded in a distorted trigonal planar geometry to three equivalent Sr2+ atoms.
