Materials Data on LaGd(BrO)2 by Materials Project
GdLa(OBr)2 crystallizes in the tetragonal P4mm space group. The structure is two-dimensional and consists of one GdLa(OBr)2 sheet oriented in the (0, 0, 1) direction. Gd3+ is bonded in a 4-coordinate geometry to four equivalent O2- and four equivalent Br1- atoms. All Gd–O bond lengths are 2.31 Å. All Gd–Br bond lengths are 3.29 Å. La3+ is bonded in a 4-coordinate geometry to four equivalent O2- and four equivalent Br1- atoms. All La–O bond lengths are 2.38 Å. All La–Br bond lengths are 3.27 Å. O2- is bonded to two equivalent Gd3+ and two equivalent La3+ atoms to form a mixture of edge and corner-sharing OLa2Gd2 tetrahedra. There are two inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a 4-coordinate geometry to four equivalent La3+ atoms. In the second Br1- site, Br1- is bonded in a 4-coordinate geometry to four equivalent Gd3+ atoms.
