Materials Data on Hg6P4PbCl6 by Materials Project
Abstract
Hg6PbP4Cl6 crystallizes in the cubic P2_13 space group. The structure is three-dimensional. there are two inequivalent Hg+1.33+ sites. In the first Hg+1.33+ site, Hg+1.33+ is bonded to two P1- and four Cl1- atoms to form HgP2Cl4 octahedra that share corners with eight HgP2Cl4 octahedra, corners with two PHg3P tetrahedra, edges with two equivalent PbCl6 octahedra, and edges with four equivalent HgP2Cl4 octahedra. The corner-sharing octahedra tilt angles range from 8–85°. Both Hg–P bond lengths are 2.50 Å. There are a spread of Hg–Cl bond distances ranging from 2.95–3.27 Å. In the second Hg+1.33+ site, Hg+1.33+ is bonded to two P1- and four Cl1- atoms to form distorted HgP2Cl4 octahedra that share corners with eight HgP2Cl4 octahedra, corners with two PHg3P tetrahedra, edges with two equivalent PbCl6 octahedra, and edges with four equivalent HgP2Cl4 octahedra. The corner-sharing octahedra tilt angles range from 8–85°. Both Hg–P bond lengths are 2.49 Å. There are a spread of Hg–Cl bond distances ranging from 2.91–3.24 Å. Pb2+ is bonded to six Cl1- atoms to form PbCl6 octahedra that share edges with twelve HgP2Cl4 octahedra. There are three shorter (2.79 Å) and three longer (3.10 Å) Pb–Cl bond lengths. There are four inequivalent P1- sites. Inmore »
