The Materials Project

KEr3F10 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. K1+ is bonded to sixteen F1- atoms to form distorted edge-sharing KF16 tetrahedra. There are four shorter (2.77 Å) and twelve longer (3.21 Å) K–F bond lengths. Er3+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are four shorter (2.20 Å) and four longer (2.36 Å) Er–F bond lengths. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a bent 150 degrees geometry to two equivalent K1+ and two equivalent Er3+ atoms. In the second F1- site, F1- is bonded to one K1+ and three equivalent Er3+ atoms to form a mixture of distorted corner and edge-sharing FKEr3 tetrahedra.
