Li Mn Mn Hg
LiMn1MnHg is gamma nitrogen-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two lithium;manganese molecules and two MnHg clusters. In each MnHg cluster, Mn(1) is bonded in a single-bond geometry to one Hg(1) atom. The Mn(1)-Hg(1) bond length is 1.14 Å. Hg(1) is bonded in a single-bond geometry to one Mn(1) atom.
