Ti Ti Ti Ti Ag Ag
Ti2Ag crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one Ti2Ag cluster. There are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded in a single-bond geometry to one Ag(1) atom. The Ti(1)-Ag(1) bond length is 1.46 Å. In the second Ti site, Ti(2) is bonded in a 2-coordinate geometry to one Ti(2) and one Ag(1) atom. The Ti(2)-Ti(2) bond length is 1.17 Å. The Ti(2)-Ag(1) bond length is 2.72 Å. Ag(1) is bonded in a distorted single-bond geometry to one Ti(1) and one Ti(2) atom.
