The material structure described by KHgC2 crystallizes in the orthorhombic Fddd space group. K(1) is bonded in a 12-coordinate geometry to six equivalent Hg(1) and six equivalent C(1) atoms. Hg(1) is bonded in a 9-coordinate geometry to six equivalent K(1) and three equivalent Hg(1) atoms. C(1) is bonded in a 4-coordinate geometry to three equivalent K(1) and two equivalent C(1) atoms. is represented by the CIF card [CIF]
