Mn2Hg(CO)10 is alpha Niobium phosphide-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two Mn2Hg(CO)10 clusters. Mn2+ is bonded to one Hg2+ and five C+1.40+ atoms to form distorted corner-sharing MnHgC5 square pyramids. The Mn–Hg bond length is 2.71 Å. There is one shorter (1.82 Å) and four longer (1.85 Å) Mn–C bond length. Hg2+ is bonded in a linear geometry to two equivalent Mn2+ atoms. There are five inequivalent C+1.40+ sites. In the first C+1.40+ site, C+1.40+ is bonded in a linear geometry to one Mn2+ and one O2- atom. The C–O bond length is 1.16 Å. In the second C+1.40+ site, C+1.40+ is bonded in a linear geometry to one Mn2+ and one O2- atom. The C–O bond length is 1.16 Å. In the third C+1.40+ site, C+1.40+ is bonded in a linear geometry to one Mn2+ and one O2- atom. The C–O bond length is 1.16 Å. In the fourth C+1.40+ site, C+1.40+ is bonded in a linear geometry to one Mn2+ and one O2- atom. The C–O bond length is 1.16 Å. In the fifth C+1.40+ site, C+1.40+ is bonded in a linear geometry to one Mn2+ and one O2- atom. The C–O bond length is 1.16 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one C+1.40+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one C+1.40+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one C+1.40+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one C+1.40+ atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to one C+1.40+ atom.
