Barium acetylacetonate is a compound with formula Ba(C5H7O2)2. It is the Ba2+ complex of the anion acetylacetonate. The compound is typically encountered as an ill-defined hydrate, which would accord with the high coordination number characteristic of barium.[1][2]
Uses

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.[4]
