Thulium acetylacetonate is a coordination compound with the formula Tm(C₅H₇O₂)₃. This anhydrous acetylacetonate complex is often discussed but unlikely to exist per se. The 8-coordinated dihydrate Tm(C₅H₇O₂)₃(H₂O)₂ is a more plausible formula based on the behavior of other lanthanide acetylacetonates. The dihydrate has been characterized by X-ray crystallography.^[3]^[4] Upon attempted dehydration by heating under vacuum, other hydrated lanthanide tris(acetylacetonate) complexes decompose to give oxo-clusters.^[5]

Thulium acetylacetonate can be prepared by the reaction of thulium hydroxide and acetylacetone.^[6] Its monohydrate is not volatile.^[7] The acetonitrile solution of its dihydrate and the dichloromethane solution of 5-[(4-fluorobenzylidene)amino]-8-hydroxyquinoline (HL) react by heating to obtain the complex [Tm₄(acac)₆(L)₆(μ₃-OH)₂].^[8]
