Materials Data on KHgSb by Materials Project
KHgSb crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. K1+ is bonded to six equivalent Sb3- atoms to form a mixture of face, edge, and corner-sharing KSb6 octahedra. The corner-sharing octahedral tilt angles are 43°. All K–Sb bond lengths are 3.86 Å. Hg2+ is bonded in a trigonal planar geometry to three equivalent Sb3- atoms. All Hg–Sb bond lengths are 2.83 Å. Sb3- is bonded in a 9-coordinate geometry to six equivalent K1+ and three equivalent Hg2+ atoms.
