Materials Data on SmBrO by Materials Project
SmOBr is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is two-dimensional and consists of one SmOBr sheet oriented in the (0, 0, 1) direction. Sm3+ is bonded in a 4-coordinate geometry to four equivalent O2- and four equivalent Br1- atoms. All Sm–O bond lengths are 2.30 Å. All Sm–Br bond lengths are 3.25 Å. O2- is bonded to four equivalent Sm3+ atoms to form a mixture of edge and corner-sharing OSm4 tetrahedra. Br1- is bonded in a 4-coordinate geometry to four equivalent Sm3+ atoms.
