Materials Data on ReB2 by Materials Project

ReB2 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Re6+ is bonded in a 8-coordinate geometry to eight equivalent B3- atoms. There are two shorter (2.23 Å) and six longer (2.27 Å) Re–B bond lengths. B3- is bonded in a 7-coordinate geometry to four equivalent Re6+ and three equivalent B3- atoms. All B–B bond lengths are 1.83 Å.
