Ti Ti Cd Si
Ti2CdSi crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ti2CdSi clusters. Ti(1) is bonded in a single-bond geometry to one Cd(1) and one Si(1) atom. The Ti(1)-Cd(1) bond length is 0.20 Å. The Ti(1)-Si(1) bond length is 0.10 Å. Cd(1) is bonded in a 3-coordinate geometry to two equivalent Ti(1) and one Si(1) atom. The Cd(1)-Si(1) bond length is 0.19 Å. Si(1) is bonded in a water-like geometry to two equivalent Ti(1) and one Cd(1) atom.
