Materials Data on SbSeI by Materials Project
SbSeI crystallizes in the orthorhombic Pnma space group. The structure is one-dimensional and consists of two SbSeI ribbons oriented in the (1, 0, 0) direction. Sb3+ is bonded to three equivalent Se2- and two equivalent I1- atoms to form edge-sharing SbSe3I2 square pyramids. There are one shorter (2.64 Å) and two longer (2.84 Å) Sb–Se bond lengths. Both Sb–I bond lengths are 3.16 Å. Se2- is bonded in a 3-coordinate geometry to three equivalent Sb3+ atoms. I1- is bonded in a distorted L-shaped geometry to two equivalent Sb3+ atoms.
