The structure described by Hg3C2(N2Cl)2 crystallizes in the orthorhombic Pca2_1 space group. There are three inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a 5-coordinate geometry to one N(1), one N(4), one Cl(1), and two equivalent Cl(2) atoms. In the second Hg site, Hg(2) is bonded in a distorted rectangular see-saw-like geometry to one N(2), one N(4), one Cl(1), and one Cl(2) atom. In the third Hg site, Hg(3) is bonded in a distorted linear geometry to one N(1), one N(3), and one Cl(2) atom. There are two inequivalent C sites. In the first C site, C(1) is bonded in a linear geometry to one N(2) and one N(4) atom. In the second C site, C(2) is bonded in a linear geometry to one N(1) and one N(3) atom. There are four inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to one Hg(1), one Hg(3), and one C(2) atom. In the second N site, N(2) is bonded in a bent 120 degrees geometry to one Hg(2) and one C(1) atom. In the third N site, N(3) is bonded in a distorted bent 120 degrees geometry to one Hg(3) and one C(2) atom. In the fourth N site, N(4) is bonded in a trigonal planar geometry to one Hg(1), one Hg(2), and one C(1) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted L-shaped geometry to one Hg(1) and one Hg(2) atom. In the second Cl site, Cl(2) is bonded in a 4-coordinate geometry to one Hg(2), one Hg(3), and two equivalent Hg(1) atoms. is represented by the CIF card [CIF]
