Na Mn Pb
NaMnPb is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NaMnPb clusters. Na(1) is bonded in a single-bond geometry to one Pb(1) atom. The Na(1)-Pb(1) bond length is 0.33 Å. Mn(1) is bonded in a single-bond geometry to one Pb(1) atom. The Mn(1)-Pb(1) bond length is 0.70 Å. Pb(1) is bonded in a linear geometry to one Na(1) and one Mn(1) atom.
