Tris(acetylacetonato)titanium(III), often abbreviated Ti(acac)₃, is a coordination complex of titanium(III) featuring acetylacetonate (acac) ligands, making it one of a family of metal acetylacetonates. It is a blue air-sensitive solid that dissolves in nonpolar organic solvents. The compound is prepared by treating titanium trichloride with acetylacetone in the presence of base.{{cite journal |doi=10.1007/s11224-016-0864-0|title=An Historic and Scientific Study of the Properties of Metal(III) Tris-acetylacetonates|year=2017|last1=Arslan|first1=Evrim|last2=Lalancette|first2=Roger A.|last3=Bernal|first3=Ivan|journal=Structural Chemistry|volume=28|pages=201–212|s2cid=99668641}} Being paramagnetic, it gives a contact-shifted proton NMR signal at 60 ppm upfield of TMS assigned to the methyl group.{{cite journal |doi=10.1021/ja01092a015|title=The Nuclear Magnetic Resonance of Some Paramagnetic Transition Metal Acetylacetonates|year=1965|last1=Eaton|first1=D.
