Zr Mn Pb
ZrMnPb crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ZrMnPb clusters. Zr(1) is bonded in a distorted linear geometry to one Mn(1) and one Pb(1) atom. The Zr(1)-Mn(1) bond length is 1.57 Å. The Zr(1)-Pb(1) bond length is 1.03 Å. Mn(1) is bonded in a distorted single-bond geometry to one Zr(1) atom. Pb(1) is bonded in a single-bond geometry to one Zr(1) atom.
