In order for undergraduate laboratory experiments to reflect modern research practice, it is essential that they include a range of elements, and that synthetic tasks are accompanied by characterization and analysis. This intermediate general chemistry laboratory exercise runs over 2 weeks, and involves the preparation of a Schiff base ligand and its metal (Fe 3+ or Cu 2+ ) complex. Students are then able to determine the metal−ligand stoichiometry of one metal− ligand pair. This experiment demonstrates that varying the transition metal can give rise to different structures, and hence different properties.

“…The strong absorption bands at 1607 and 1639 cm ¡1 can be attributed to n(CHN) and n(CHO), respectively. [27] The complex also exhibits a stretching frequency at 863 cm ¡1 , which can be attributed to FeÀ ÀOÀ ÀFe asymmetric stretching. [28,29] The observed bands in the range of 660-710 cm ¡1 are characteristic of n(CÀ ÀCl) vibrations of the ligands.…”

A series of new homo-binuclear nano Mn(II), Fe (III), Co(II), Ni(II), and Cu(II) complexes were synthesized using a Schiff base ligand derived by condensation of p-phenylenediamine with 2-hydroxy-1-naphthaldehyde. The prepared complexes were characterized using elemental, thermal analyses, FTIR, 1 HNMR, 13 CNMR, UV-Vis, XRD, SEM, molar conductance, and magnetic moment measurements. FTIR spectral studies revealed the interaction of the ligand as bi-negative tetra-dentate towards Mn(II) and Fe(III) atoms, whereas the ligand molecule coordinates in neutral tetra-dentate mode towards Co(II), Ni(II), and Cu (II) ions. The geometries proposed are mainly octahedral configuration surrounds the central atoms referring to the electronic spectral data and magnetic measurements. The calculations abstracted from XRD patterns propose the nano-sized complexes. The SEM images show the nanosized appearance of the particles except for the Ni(II)-complex. Thermo-gravimetric analysis was used to ensure the nature of the presence of solvent molecules attaching to the complexes. Molecular modeling was performed to assert the structural formula proposed for the ligand and some of its complexes. Also, drug-likeness was theoretically estimated to display the probable biological activity of the free ligand through a theoretical comparison with known drugs.
