Materials Data on In3Hg by Materials Project

HgIn3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Hg is bonded in a distorted hexagonal planar geometry to twelve equivalent In atoms. There are six shorter (3.29 Å) and six longer (3.49 Å) Hg–In bond lengths. In is bonded to four equivalent Hg and eight equivalent In atoms to form a mixture of distorted corner, edge, and face-sharing InIn8Hg4 cuboctahedra. There are a spread of In–In bond distances ranging from 3.27–3.50 Å.

Materials Data on In3Hg by Materials Project

HgIn2In crystallizes in the orthorhombic Cmmm space group. The structure is two-dimensional and consists of two indium molecules and one HgIn2 sheet oriented in the (0, 0, 1) direction. In the HgIn2 sheet, Hg is bonded in a distorted rectangular see-saw-like geometry to four equivalent In atoms. All Hg–In bond lengths are 2.94 Å. In is bonded in a 4-coordinate geometry to two equivalent Hg and two equivalent In atoms. Both In–In bond lengths are 2.90 Å.
