Materials Data on SbSeBr by Materials Project
SbSeBr crystallizes in the orthorhombic Pnma space group. The structure is one-dimensional and consists of two SbSeBr ribbons oriented in the (1, 0, 0) direction. Sb3+ is bonded to three equivalent Se2- and two equivalent Br1- atoms to form edge-sharing SbSe3Br2 square pyramids. There are one shorter (2.65 Å) and two longer (2.83 Å) Sb–Se bond lengths. Both Sb–Br bond lengths are 2.97 Å. Se2- is bonded in a 3-coordinate geometry to three equivalent Sb3+ atoms. Br1- is bonded in a distorted L-shaped geometry to two equivalent Sb3+ atoms.
