text: # Titanium bis(acetylacetonate)dichloride
  
  Titanium bis(acetylacetonate)dichloride is the coordination complex with the formula $Ti(C_5H_7O_2)_2Cl_2.$ It is a common acetylacetonate complex of titanium. It is a red-orange solid that hydrolyzes slowly in air.
  
  The complex is prepared by treatment of titanium tetrachloride with excess acetylacetone:
  
      $TiCl_4$ + 2 Hacac → $Ti(acac)_2Cl_2$ + 2 HCl
  
  It is an octahedral complex that crystallizes as a racemic mixture of the chiral cis isomers. It is fluxional in solution, as the result of rapid cis–trans equilibrium.
