Barium acetylacetonate is a compound with formula Ba(C5H7O2)2.

The compound is typically encountered as an ill-defined hydrate, which would accord with the high coordination number characteristic of barium.

[1][2] Barium acetylacetonate has been examined in metal organic chemical vapour deposition of BaTiO3 thin films.

[3] The related complex with hexafluoroacetylacetonate Ba(hfa)2(tetraglyme) has also been investigated.

Its formation of a sublimable adduct containing a polyether illustrates the high coordination numbers typical of barium.
