Mo2MnPb crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Mo2MnPb clusters. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded in a single-bond geometry to one Mn(1) atom. The Mo(1)-Mn(1) bond length is 2.43 Å. In the second Mo site, Mo(2) is bonded in a single-bond geometry to one Pb(1) atom. The Mo(2)-Pb(1) bond length is 0.05 Å. Mn(1) is bonded in a distorted linear geometry to one Mo(1) and one Pb(1) atom. The Mn(1)-Pb(1) bond length is 1.75 Å. Pb(1) is bonded in a distorted linear geometry to one Mo(2) and one Mn(1) atom.
