The crystal structure described by Hg(CO2)2 is alpha structured and crystallizes in the monoclinic P2_1 space group. The structure is zero-dimensional and consists of two mercuric formate molecules. Hg(1) is bonded in a linear geometry to one O(2) and one O(3) atom. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to one O(3) and one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one C(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Hg(1) and one C(1) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Hg(1) and one C(2) atom. In the fourth O site, O(4) is bonded in a single-bond geometry to one C(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
