Abstract

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.
