Titanium(II) chloride is the chemical compound with the formula TiCl₂. The black solid has been studied only moderately, probably because of its high reactivity. Ti(II) is a strong reducing agent: it has a high affinity for oxygen and reacts irreversibly with water to produce H₂. The usual preparation is the thermal disproportionation of TiCl₃ at 500 °C. The equilibrium is "driven" by the loss of volatile TiCl₄:

2 TiCl₃ → TiCl₂ + TiCl₄

The method is similar to that for the conversion of VCl₃ into VCl₂ and VCl₄.

TiCl₂ crystallizes as the layered CdI₂ structure. Thus, the Ti(II) centers are octahedrally coordinated to six chloride ligands
