Materials Data on CdHgS4 by Materials Project
CdHgS4 crystallizes in the tetragonal I-4 space group. The structure is three-dimensional and consists of two cadmium molecules and one HgS4 framework. In the HgS4 framework, Hg2+ is bonded in a 8-coordinate geometry to two equivalent Hg2+ and eight equivalent S1- atoms. Both Hg–Hg bond lengths are 3.01 Å. There are four shorter (3.29 Å) and four longer (3.32 Å) Hg–S bond lengths. S1- is bonded in a 4-coordinate geometry to two equivalent Hg2+ and two equivalent S1- atoms. Both S–S bond lengths are 2.15 Å.
