Materials Data on PaB3 by Materials Project
PaB3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Pa3+ is bonded in a 12-coordinate geometry to twelve equivalent B1- atoms. There are six shorter (2.70 Å) and six longer (2.77 Å) Pa–B bond lengths. B1- is bonded in a 10-coordinate geometry to four equivalent Pa3+ and six equivalent B1- atoms. There is two shorter (1.84 Å) and four longer (2.02 Å) B–B bond length.
