Materials Data on Pr2CBr by Materials Project
Pr2CBr is H-Phase structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Pr is bonded to three equivalent C and three equivalent Br atoms to form a mixture of distorted face, edge, and corner-sharing PrC3Br3 octahedra. The corner-sharing octahedra tilt angles range from 0–40°. All Pr–C bond lengths are 2.62 Å. All Pr–Br bond lengths are 3.25 Å. C is bonded to six equivalent Pr atoms to form edge-sharing CPr6 octahedra. Br is bonded in a 6-coordinate geometry to six equivalent Pr atoms.
