Materials Data on Pr3RhBr3 by Materials Project
Pr3RhBr3 crystallizes in the cubic I4_132 space group. The structure is three-dimensional. Pr is bonded to two equivalent Rh and four equivalent Br atoms to form a mixture of corner and edge-sharing PrRh2Br4 octahedra. The corner-sharing octahedra tilt angles range from 5–8°. Both Pr–Rh bond lengths are 2.86 Å. There are two shorter (3.13 Å) and two longer (3.24 Å) Pr–Br bond lengths. Rh is bonded to six equivalent Pr atoms to form edge-sharing RhPr6 octahedra. Br is bonded in a rectangular see-saw-like geometry to four equivalent Pr atoms.
