KHg crystallizes in the triclinic P-1 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to four equivalent Hg(1) and four equivalent Hg(2) atoms. In the second K site, K(2) is bonded in a 7-coordinate geometry to three equivalent Hg(1) and four equivalent Hg(2) atoms. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a 9-coordinate geometry to three equivalent K(2), four equivalent K(1), and two equivalent Hg(2) atoms. In the second Hg site, Hg(2) is bonded in a 10-coordinate geometry to four equivalent K(1), four equivalent K(2), and two equivalent Hg(1) atoms.
KHg crystallizes in the triclinic P-1 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to four equivalent Hg(1) and four equivalent Hg(2) atoms. There are a spread of K(1)-Hg(1) bond distances ranging from 3.53-3.93 Å. There are a spread of K(1)-Hg(2) bond distances ranging from 3.61-3.93 Å. In the second K site, K(2) is bonded in a 7-coordinate geometry to three equivalent Hg(1) and four equivalent Hg(2) atoms. There are a spread of K(2)-Hg(1) bond distances ranging from 3.59-3.65 Å. There are a spread of K(2)-Hg(2) bond distances ranging from 3.56-3.87 Å. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a 9-coordinate geometry to three equivalent K(2), four equivalent K(1), and two equivalent Hg(2) atoms. There is one shorter (3.01 Å) and one longer (3.04 Å) Hg(1)-Hg(2) bond length. In the second Hg site, Hg(2) is bonded in a 10-coordinate geometry to four equivalent K(1), four equivalent K(2), and two equivalent Hg(1) atoms.
