The crystal structure described by (KHgC2N2O)2Cl2 crystallizes in the orthorhombic Pnma space group. The structure consists of four hydrochloric acid atoms inside a KHgC2N2O framework. In the KHgC2N2O framework, K(1) is bonded in a 7-coordinate geometry to two equivalent N(1), three equivalent N(2), and two equivalent O(1) atoms. Hg(1) is bonded in a linear geometry to one C(1) and one C(2) atom. There are two inequivalent C sites. In the first C site, C(1) is bonded in a linear geometry to one Hg(1) and one N(1) atom. In the second C site, C(2) is bonded in a linear geometry to one Hg(1) and one N(2) atom. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted single-bond geometry to two equivalent K(1) and one C(1) atom. In the second N site, N(2) is bonded in a distorted single-bond geometry to three equivalent K(1) and one C(2) atom. O(1) is bonded in a distorted water-like geometry to two equivalent K(1) atoms. is represented by the CIF card [CIF]
