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:
Additional recommended knowledge
Unusual electronic effects have been observed in these species: TiCl2[(CH3)2PCH2CH2P(CH3)2]2 is paramagnetic with a triplet ground state, but Ti(CH3)2[(CH3)2PCH2CH2P(CH3)2]2 is diamagnetic.
A solid-state derivative of TiCl2 is Na2TiCI4, which has been prepared by the reaction of Ti metal with TiCl3 in a NaCl flux. This species adopts a linear chain structure wherein again the Ti(II) centers are octahedral with terminal, axial halides.
