Pr2B3Cl crystallizes in the hexagonal P6_3/mmc space group. Pr(1) is bonded in a 9-coordinate geometry to six equivalent B(1) and three equivalent Cl(1) atoms. B(1) is bonded in a body-centered cubic geometry to four equivalent Pr(1) and four equivalent B(1) atoms. Cl(1) is bonded in a 6-coordinate geometry to six equivalent Pr(1) atoms.
Pr2B3Cl crystallizes in the hexagonal P6_3/mmc space group. Pr(1) is bonded in a 9-coordinate geometry to six equivalent B(1) and three equivalent Cl(1) atoms. All Pr(1)-B(1) bond lengths are 2.80 Å. All Pr(1)-Cl(1) bond lengths are 3.09 Å. B(1) is bonded in a body-centered cubic geometry to four equivalent Pr(1) and four equivalent B(1) atoms. There are two shorter (1.79 Å) and two longer (1.80 Å) B(1)-B(1) bond lengths. Cl(1) is bonded in a 6-coordinate geometry to six equivalent Pr(1) atoms.
