Editing Titanium tetrachloride (section)

===Complexes with simple ligands===
{{chem2|TiCl4}} is a [[Lewis acid]] as implicated by its tendency to [[hydrolysis|hydrolyze]]. With the [[ether]] [[tetrahydrofuran|THF]], {{chem2|TiCl4}} reacts to give yellow crystals of {{chem2|TiCl4(THF)2}}. With chloride salts, {{chem2|TiCl4}} reacts to form sequentially {{chem2|[Ti2Cl9]−}}, {{chem2|[Ti2Cl10](2−)}} (see figure above), and {{chem2|[TiCl6](2−)}}.<ref>{{cite journal|first1= C.

These reactions highlight the influence of electrostatics on the structures of compounds with highly ionic bonding.
