Ti Ti Tc
Ti2Tc is Cyanogen Chloride-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ti2Tc clusters. There are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded in a single-bond geometry to one Ti(2) atom. The Ti(1)-Ti(2) bond length is 0.43 Å. In the second Ti site, Ti(2) is bonded in a linear geometry to one Ti(1) and one Tc(1) atom. The Ti(2)-Tc(1) bond length is 1.30 Å. Tc(1) is bonded in a single-bond geometry to one Ti(2) atom.
