PrHg3 crystallizes in the hexagonal P6_3/mmc space group. Pr(1) is bonded to twelve equivalent Hg(1) atoms to form a mixture of face and corner-sharing PrHg12 cuboctahedra. Hg(1) is bonded in a 4-coordinate geometry to four equivalent Pr(1) atoms.
PrHg3 crystallizes in the hexagonal P6_3/mmc space group. Pr(1) is bonded to twelve equivalent Hg(1) atoms to form a mixture of face and corner-sharing PrHg12 cuboctahedra. There are six shorter (3.23 Å) and six longer (3.41 Å) Pr(1)-Hg(1) bond lengths. Hg(1) is bonded in a 4-coordinate geometry to four equivalent Pr(1) atoms.
