Chemical compound
Titanium bis(acetylacetonate)dichloride is the coordination complex with the formula Ti(C5H7O2)2Cl2. It is a common acetylacetonate complex of titanium. It is a red-orange solid that hydrolyzes slowly in air.[1]
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]
