Materials Data on CrSBr by Materials Project
CrSBr crystallizes in the orthorhombic Pmmn space group. The structure is two-dimensional and consists of one CrSBr sheet oriented in the (0, 0, 1) direction. Cr3+ is bonded to four equivalent S2- and two equivalent Br1- atoms to form a mixture of corner and edge-sharing CrS4Br2 octahedra. The corner-sharing octahedral tilt angles are 22°. There are two shorter (2.39 Å) and two longer (2.42 Å) Cr–S bond lengths. Both Cr–Br bond lengths are 2.53 Å. S2- is bonded to four equivalent Cr3+ atoms to form a mixture of distorted corner and edge-sharing SCr4 trigonal pyramids. Br1- is bonded in an L-shaped geometry to two equivalent Cr3+ atoms.
