Materials Data on Sr(InHg)2 by Materials Project
Sr(HgIn)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Sr is bonded in a 8-coordinate geometry to eight equivalent Hg atoms. All Sr–Hg bond lengths are 3.57 Å. Hg is bonded in a 9-coordinate geometry to four equivalent Sr, one Hg, and four equivalent In atoms. The Hg–Hg bond length is 2.85 Å. All Hg–In bond lengths are 3.00 Å. In is bonded to four equivalent Hg atoms to form a mixture of distorted edge and corner-sharing InHg4 tetrahedra.
