Materials Data on Hg2H10C3NCl5 by Materials Project
Hg2Cl5C3H7NH3 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of two trimethylazanium molecules and one Hg2Cl5 sheet oriented in the (0, 1, 0) direction. In the Hg2Cl5 sheet, there are two inequivalent Hg2+ sites. In the first Hg2+ site, Hg2+ is bonded in a 6-coordinate geometry to six Cl1- atoms. There are a spread of Hg–Cl bond distances ranging from 2.36–3.41 Å. In the second Hg2+ site, Hg2+ is bonded to five Cl1- atoms to form a mixture of distorted edge and corner-sharing HgCl5 trigonal bipyramids. There are a spread of Hg–Cl bond distances ranging from 2.41–3.23 Å. There are five inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a single-bond geometry to one Hg2+ atom. In the second Cl1- site, Cl1- is bonded in a distorted single-bond geometry to two equivalent Hg2+ atoms. In the third Cl1- site, Cl1- is bonded in a distorted T-shaped geometry to three Hg2+ atoms. In the fourth Cl1- site, Cl1- is bonded in a single-bond geometry to one Hg2+ atom. In the fifth Cl1- site, Cl1- is bonded in a distorted see-saw-like geometry to four Hg2+ atoms.
