Title: Materials Data on CdHgSe2 by Materials Project

Abstract

HgCdSe2 is Lavarevi\'{c}ite-like structured and crystallizes in the trigonal R3m space group. The structure is three-dimensional. Hg2+ is bonded to four Se2- atoms to form HgSe4 tetrahedra that share corners with six equivalent HgSe4 tetrahedra and corners with six equivalent CdSe4 tetrahedra. There are three shorter (2.71 Å) and one longer (2.72 Å) Hg–Se bond lengths. Cd2+ is bonded to four Se2- atoms to form CdSe4 tetrahedra that share corners with six equivalent HgSe4 tetrahedra and corners with six equivalent CdSe4 tetrahedra. There are one shorter (2.69 Å) and three longer (2.70 Å) Cd–Se bond lengths. There are two inequivalent Se2- sites. In the first Se2- site, Se2- is bonded to one Hg2+ and three equivalent Cd2+ atoms to form corner-sharing SeCd3Hg tetrahedra. In the second Se2- site, Se2- is bonded to three equivalent Hg2+ and one Cd2+ atom to form corner-sharing SeCdHg3 tetrahedra.
