Yttrium acetylacetonate is a coordination compound of yttrium, with the chemical formula of Y(C5H7O2)3, or Y(acac)3 for short. Its instability constants (logYn) are 2.08, 3.81 and 4.98 (n=1, 2, 3).[2] It can be prepared by the reaction of trialkoxyyttrium[3] or tris[bis(trimethylsilyl) amino]yttrium[4] and acetylacetone. It thermally decomposes to form yttrium oxide.[5]
