PrZr2F11 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(3) atoms. Zr(1) is bonded to one F(4), two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form distorted corner-sharing ZrF7 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 Zr(1) atom. In the second F site, F(2) is bonded in a bent 150 degrees geometry to two equivalent Zr(1) atoms. In the third F site, F(3) is bonded in a bent 150 degrees geometry to one Pr(1) and one Zr(1) atom. In the fourth F site, F(4) is bonded in a linear geometry to two equivalent Zr(1) atoms.
PrZr2F11 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(3) atoms. All Pr(1)-F(1) bond lengths are 2.38 Å. All Pr(1)-F(3) bond lengths are 2.39 Å. Zr(1) is bonded to one F(4), two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form distorted corner-sharing ZrF7 pentagonal bipyramids. The Zr(1)-F(4) bond length is 2.10 Å. Both Zr(1)-F(1) bond lengths are 2.04 Å. There is one shorter (2.09 Å) and one longer (2.11 Å) Zr(1)-F(2) bond length. Both Zr(1)-F(3) bond lengths are 2.04 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 Zr(1) atom. In the second F site, F(2) is bonded in a bent 150 degrees geometry to two equivalent Zr(1) atoms. In the third F site, F(3) is bonded in a bent 150 degrees geometry to one Pr(1) and one Zr(1) atom. In the fourth F site, F(4) is bonded in a linear geometry to two equivalent Zr(1) atoms.
