Materials Data on UReB3 by Materials Project
UReB3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. U6+ is bonded in a 12-coordinate geometry to twelve equivalent B3- atoms. There are six shorter (2.58 Å) and six longer (2.75 Å) U–B bond lengths. Re3+ is bonded to six equivalent B3- atoms to form face-sharing ReB6 octahedra. All Re–B bond lengths are 2.32 Å. B3- is bonded in a 8-coordinate geometry to four equivalent U6+, two equivalent Re3+, and two equivalent B3- atoms. Both B–B bond lengths are 1.73 Å.
