The structure described by LaZr2F11 crystallizes in the orthorhombic Ibam space group. La(1) is bonded in a 8-coordinate geometry to four equivalent F(3) and four equivalent F(4) atoms. Zr(1) is bonded to one F(1), two equivalent F(2), two equivalent F(3), and two equivalent F(4) 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 linear geometry to two equivalent Zr(1) atoms. 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 La(1) and one Zr(1) atom. In the fourth F site, F(4) is bonded in a bent 150 degrees geometry to one La(1) and one Zr(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
