Zr Nb Pb Pb
ZrNb(Pb)2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one lead molecule and one ZrNb cluster. In the ZrNb cluster, Zr(1) is bonded in a distorted single-bond geometry to one Nb(1) atom. The Zr(1)-Nb(1) bond length is 0.78 Å. Nb(1) is bonded in a distorted single-bond geometry to one Zr(1) atom.
