The crystal structure described by KHgC2N2I crystallizes in the orthorhombic Cmcm space group. K(1) is bonded in a 4-coordinate geometry to four equivalent N(1) and two equivalent I(1) atoms. Hg(1) is bonded in a linear geometry to two equivalent C(1) and four equivalent I(1) atoms. C(1) is bonded in a linear geometry to one Hg(1) and one N(1) atom. N(1) is bonded in a distorted single-bond geometry to two equivalent K(1) and one C(1) atom. I(1) is bonded in a 6-coordinate geometry to two equivalent K(1) and four equivalent Hg(1) atoms. is represented by the CIF file [CIF]
