PrHf2F11 crystallizes in the orthorhombic Ibam space group. Pr(1) is bonded in a 8-coordinate geometry to four equivalent F(1) and four equivalent F(4) atoms. Hf(1) is bonded to one F(2), two equivalent F(1), two equivalent F(3), and two equivalent F(4) atoms to form distorted corner-sharing HfF7 pentagonal bipyramids. There are four inequivalent F sites. In the first F site, F(1) is bonded in a bent 150 degrees geometry to one Pr(1) and one Hf(1) atom. In the second F site, F(2) is bonded in a linear geometry to two equivalent Hf(1) atoms. In the third F site, F(3) is bonded in a linear geometry to two equivalent Hf(1) atoms. In the fourth F site, F(4) is bonded in a bent 150 degrees geometry to one Pr(1) and one Hf(1) atom.
PrHf2F11 crystallizes in the orthorhombic Ibam space group. Pr(1) is bonded in a 8-coordinate geometry to four equivalent F(1) and four equivalent F(4) atoms. All Pr(1)-F(1) bond lengths are 2.39 Å. All Pr(1)-F(4) bond lengths are 2.38 Å. Hf(1) is bonded to one F(2), two equivalent F(1), two equivalent F(3), and two equivalent F(4) atoms to form distorted corner-sharing HfF7 pentagonal bipyramids. The Hf(1)-F(2) bond length is 2.07 Å. Both Hf(1)-F(1) bond lengths are 2.02 Å. There is one shorter (2.06 Å) and one longer (2.08 Å) Hf(1)-F(3) bond length. Both Hf(1)-F(4) bond lengths are 2.01 Å. There are four inequivalent F sites. In the first F site, F(1) is bonded in a bent 150 degrees geometry to one Pr(1) and one Hf(1) atom. In the second F site, F(2) is bonded in a linear geometry to two equivalent Hf(1) atoms. In the third F site, F(3) is bonded in a linear geometry to two equivalent Hf(1) atoms. In the fourth F site, F(4) is bonded in a bent 150 degrees geometry to one Pr(1) and one Hf(1) atom.
