Abstract

Hg crystallizes in the orthorhombic Ama2 space group. The structure is three-dimensional and consists of eight mercury molecules and one Hg framework. In the Hg framework, there are ten inequivalent Hg sites. In the first Hg site, Hg is bonded in a 5-coordinate geometry to five Hg atoms. There are a spread of Hg–Hg bond distances ranging from 3.28–3.33 Å. In the second Hg site, Hg is bonded in a 5-coordinate geometry to five Hg atoms. There are a spread of Hg–Hg bond distances ranging from 3.28–3.34 Å. In the third Hg site, Hg is bonded in a 5-coordinate geometry to five Hg atoms. There are a spread of Hg–Hg bond distances ranging from 3.28–3.34 Å. In the fourth Hg site, Hg is bonded in a 6-coordinate geometry to six Hg atoms. There are two shorter (3.25 Å) and two longer (3.26 Å) Hg–Hg bond lengths. In the fifth Hg site, Hg is bonded in a 6-coordinate geometry to six Hg atoms. There are two shorter (3.25 Å) and two longer (3.26 Å) Hg–Hg bond lengths. In the sixth Hg site, Hg is bonded in a 6-coordinate geometry to six Hg atoms. All Hg–Hg bond lengths are 3.25 Å. In the seventh Hg site, Hg is bonded in a distorted hexagonal planar geometry to six Hg atoms. Both Hg–Hg bond lengths are 3.32 Å. In the eighth Hg site, Hg is bonded in a distorted hexagonal planar geometry to six Hg atoms. Both Hg–Hg bond lengths are 3.32 Å. In the ninth Hg site, Hg is bonded in a distorted hexagonal planar geometry to six Hg atoms. In the tenth Hg site, Hg is bonded in a distorted hexagonal planar geometry to six Hg atoms.
