General description

1,5-Diphenyl-1,3,5-pentanetrione (H2DBA, DBAc) is a symmetrical triketone.1,3,5-triketones are potential tridentate ligands and forms complexes with transition metals, lanthanides and actinides. It acts as ligand and forms binuclear cobalt complex with CoCl2.6H2O. The interaction of two intramolecular hydrogen bonds in 1,5-diphenyl-1,3,5-pentanetrione has been studied. H2DBA can be synthesized by condensation reaction between ethyl benzoate and benzoyl acetone. DBAc arranged in stretched polyethylene (PE) sheets has been investigated by infrared linear dichroism (LD) spectroscopy.
