AgZrPbZr1 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two AgZr clusters and two PbZr1 clusters. In each AgZr cluster, Zr(1) is bonded in a single-bond geometry to one Ag(1) atom. The Zr(1)-Ag(1) bond length is 0.61 Å. Ag(1) is bonded in a distorted single-bond geometry to one Zr(1) atom. In each PbZr1 cluster, Zr(2) is bonded in a distorted single-bond geometry to one Pb(1) atom. The Zr(2)-Pb(1) bond length is 1.00 Å. Pb(1) is bonded in a single-bond geometry to one Zr(2) atom.
