Title: Materials Data on K2Hg7 by Materials Project

Abstract

K2Hg7 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. K is bonded in a 12-coordinate geometry to twelve equivalent Hg atoms. There are a spread of K–Hg bond distances ranging from 3.73–3.82 Å. There are two inequivalent Hg sites. In the first Hg site, Hg is bonded in a distorted octahedral geometry to six equivalent Hg atoms. All Hg–Hg bond lengths are 3.13 Å. In the second Hg site, Hg is bonded in a 9-coordinate geometry to four equivalent K and five Hg atoms. There are two shorter (3.15 Å) and two longer (3.24 Å) Hg–Hg bond lengths.
