In this study, a new oxazoline derivative containing 2-phenyl-2-(pyridine-2-yl) oxazoline-3-yl)ethanol (POE) was synthesized from the solvent-free reaction of diethanolamine with 2-benzoylpyridine under microwave conditions. The POE ligand can coordinate to the metal through the amino and pyridine nitrogen atoms. The complexes [Ni(POE)Cl2(H2O)2] and [Cu(POE)2Br2] were synthesized from the reaction of the POE ligand with nickel chloride hexahydrate and copper bromide tetrahydrate, respectively. These complexes were characterized by elemental analysis, FT-IR, UV-Vis, conductivity, and melting point methods. Elemental analysis of the [Ni(POE)Cl2(H2O)2] and [Cu(POE)2Br2] complexes indicates that the POE to nickel and copper metal ratio is 1:1 and 1:2, respectively. In the FT-IR spectrum of the POE ligand, the stretching vibration of C=O in the starting materials 2-benzoylpyridine and NH2 in diethanolamine are absent, and a new C=N stretching vibration is observed. The vibrational bands of Ni-O, Ni-N, and Ni-Cl in the [Ni(POE)Cl2(H2O)2] complex and Cu-Br and Cu-N in the [Cu(POE)2Br2] complex are observed. The electrical conductivity of the complexes indicates that they are neutral.
