Materials Data on Na2YHgF6 by Materials Project
(Na)2YHgF6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional and consists of eight sodium molecules and one YHgF6 framework. In the YHgF6 framework, Y3+ is bonded to six equivalent F1- atoms to form YF6 octahedra that share corners with six equivalent HgF6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Y–F bond lengths are 2.17 Å. Hg1+ is bonded to six equivalent F1- atoms to form HgF6 octahedra that share corners with six equivalent YF6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Hg–F bond lengths are 2.52 Å. F1- is bonded in a linear geometry to one Y3+ and one Hg1+ atom.
