  Barium acetylacetonate is a compound with formula $Ba(C_5H_7O_2)_2.$ It is the $Ba^{2+}$ 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.
  
  ## Uses
  
      Structure of gaseous barium acetylacetonate.
  
  Barium acetylacetonate has been examined in metal organic chemical vapour deposition of $BaTiO_3$ thin films. 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.
