Materials Data on CrInBr3 by Materials Project
CrInBr3 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of two CrInBr3 sheets oriented in the (0, 1, 0) direction. Cr2+ is bonded to six Br1- atoms to form distorted edge-sharing CrBr6 octahedra. There are a spread of Cr–Br bond distances ranging from 2.51–3.28 Å. In1+ is bonded in a 5-coordinate geometry to five Br1- atoms. There are a spread of In–Br bond distances ranging from 3.16–3.52 Å. There are three inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a 2-coordinate geometry to one Cr2+ and two equivalent In1+ atoms. In the second Br1- site, Br1- is bonded in a 2-coordinate geometry to three equivalent Cr2+ atoms. In the third Br1- site, Br1- is bonded in a 1-coordinate geometry to two equivalent Cr2+ and three equivalent In1+ atoms.
