Ti Pt Pt
TiPt2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two TiPt2 clusters. Ti(1) is bonded in a distorted linear geometry to one Pt(1) and one Pt(2) atom. The Ti(1)-Pt(1) bond length is 0.08 Å. The Ti(1)-Pt(2) bond length is 1.33 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a single-bond geometry to one Ti(1) atom. In the second Pt site, Pt(2) is bonded in a single-bond geometry to one Ti(1) atom.
