Materials Data on DySBr by Materials Project
DySBr crystallizes in the orthorhombic Pmmn space group. The structure is two-dimensional and consists of one DySBr sheet oriented in the (0, 0, 1) direction. Dy3+ is bonded to four equivalent S2- and two equivalent Br1- atoms to form a mixture of edge and corner-sharing DyS4Br2 octahedra. The corner-sharing octahedral tilt angles are 21°. There are two shorter (2.73 Å) and two longer (2.74 Å) Dy–S bond lengths. Both Dy–Br bond lengths are 2.83 Å. S2- is bonded to four equivalent Dy3+ atoms to form a mixture of edge and corner-sharing SDy4 trigonal pyramids. Br1- is bonded in an L-shaped geometry to two equivalent Dy3+ atoms.
