2-Benzoylpyridine N-4-substituted thiosemicarbazones commonly coordinate as neutral tridentate ligands to give five coordinate [Cu(HL)Cl-2] complexes when prepared in boiling isopropanol. However, when prepared in boiling ethanol, the anion (loss of the N-3-hydrogen) coordinates as a tridentate ligand to give [CuLCl] complexes. Representative crystal structures of both stoichiometries have been determined. Spectral characterization of both the 2-benzoylpyridine N-4-substituted thiosemicarbazones and their copper(II) complexes includes IR, UV-vis, EPR and NMR studies. Growth inhibition studies of the thiosemicarbazones and their complexes were performed against two human pathogenic fungi.
