Materials Data on PrB2Ir3 by Materials Project
PrIr3B2 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Pr is bonded in a 12-coordinate geometry to two equivalent Pr, twelve equivalent Ir, and six equivalent B atoms. Both Pr–Pr bond lengths are 3.18 Å. All Pr–Ir bond lengths are 3.19 Å. All Pr–B bond lengths are 3.20 Å. Ir is bonded in a distorted square co-planar geometry to four equivalent Pr and four equivalent B atoms. All Ir–B bond lengths are 2.25 Å. B is bonded in a 6-coordinate geometry to three equivalent Pr and six equivalent Ir atoms.
