Thulium acetylacetonate is a coordination complex with the chemical formula Tm(C₅H₇O₂)₃, or Tm(acac)₃ for short. It can be prepared by the reaction of thulium hydroxide and ethanol solution of acetylacetone.[3] Its monohydrate is not volatile in vacuum.[4] 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].[5]
