The complexes have been characterized by elemental analysis, LC-MS, FT-IR, 1H NMR spectroscopy. Spectroscopic studies show that 5msalmsh and 5mafmsh behave monodentate ligand and coordinate via an imine N donor atom to the central metal atom in (1a) (4a) and (1b) (4b). © 2021 Slovensko Kemijsko Drustvo.
