The used ligand Acetylacetone is often abbreviated (acac), complex was isolated as pale yellow crystals from the reaction of La(NO3)3.6H2O metal salt with Acetylacetone at room temperature .The molecular formula of tris(acetylacetonatodiaqua)lanthanum(III) complex elucidated by the XRD, i.r and UV-Visible techniques .The La3+ is linked by eight oxygen donor atoms of three acetylacetone anions that behaves as bidentate ligands, and two oxygen donor atoms of water molecules acting as monodentate ligand. In this research (NO3- ) didn’t participate in coordination despite the use of the La3+nitrate salt type of the metal , while in other similar researches nitrate ion linked with two oxygen atoms acts as a bidentate ligand. The geometrical structure of the metal chelate was distorted cubic.
