The material described by NdHf2F11 crystallizes in the orthorhombic Ibam space group. Nd(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 Nd(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 bent 150 degrees geometry to two equivalent Hf(1) atoms. In the fourth F site, F(4) is bonded in a bent 150 degrees geometry to one Nd(1) and one Hf(1) atom. is represented by the CIF card [CIF]
