The complex is prepared by treatment of titanium tetrachloride with excess acetylacetone:^[1]

TiCl₄ + 2 Hacac → Ti(acac)₂Cl₂ + 2 HCl

It is an octahedral complex that crystallizes as a racemic mixture of the chiral cis isomers.^[2] It is fluxional in solution, as the result of rapid cis–trans equilibrium.^[3]
