Mn V V Pb
V2MnPb crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two V2MnPb clusters. There are two inequivalent V sites. In the first V site, V(1) is bonded in a single-bond geometry to one Pb(1) atom. The V(1)-Pb(1) bond length is 1.11 Å. In the second V site, V(2) is bonded in a distorted single-bond geometry to one Mn(1) atom. The V(2)-Mn(1) bond length is 2.64 Å. Mn(1) is bonded in a single-bond geometry to one V(2) and one Pb(1) atom. The Mn(1)-Pb(1) bond length is 0.20 Å. Pb(1) is bonded in a distorted linear geometry to one V(1) and one Mn(1) atom.
