Ti Ag Pb Pb
PbTiAgPb crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two AgPb clusters and two PbTi clusters. In each AgPb cluster, Ag(1) is bonded in a distorted single-bond geometry to one Pb(2) atom. The Ag(1)-Pb(2) bond length is 1.83 Å. Pb(2) is bonded in a 1-coordinate geometry to one Ag(1) atom. In each PbTi cluster, Ti(1) is bonded in a single-bond geometry to one Pb(1) atom. The Ti(1)-Pb(1) bond length is 1.38 Å. Pb(1) is bonded in a single-bond geometry to one Ti(1) atom.
