The goal of the following experiment was to synthesize a new tripodal ligand (abbreviated 2-OHnaphthtren) and complex it with europium(III). Two different methods of the synthesis were carried out: one synthesizing the ligand first and then adding the europium salt and another that makes the ligand and complex in situ. The first method combined tris(2-aminoethyl)amine (tren) and 3-hyrdoxynaphthalene-2-carboxaldehyde forming 2-OHnaphthtren. To form the europium(III) complex, Eu(NO3)3●6H2O was added to the ligand. The second method combined the lanthanide salt and 3-hydroxynaphthalene-2-carboxaldehyde first before adding the tren. Both 2-OHnaphthtren and its europium(III) complex were analyzed via x-ray crystallography. The ligand crystallizes in the P-1 space group with two symmetry equivalent positions within the unit cell.
