Materials Data on HgI3 by Materials Project

Kristin Persson
HgI(I)2 crystallizes in the tetragonal I4/mmm space group. The structure is two-dimensional and consists of two HgI sheets oriented in the (0, 0, 1) direction and two I sheets oriented in the (0, 0, 1) direction. In each HgI sheet, Hg is bonded in a square co-planar geometry to four equivalent I atoms. All Hg–I bond lengths are 3.19 Å. I is bonded in a square co-planar geometry to four equivalent Hg atoms. In each...
