Ti Fe Fe Pb
(Fe)2PbTi crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two iron molecules and two PbTi clusters. 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 0.78 Å. Pb(1) is bonded in a single-bond geometry to one Ti(1) atom.
