Structural investigation of Fe(III) and Ga(III) complexes with aromatic hydrazones by ESI MS/MS

Aroylhydrazones can act as neutral, monoanionic or dianionic ONO tridentate ligands [1]. The coordination abilities of aromatic hydrazones derived from nicotinic acid hydrazide and differently substituted 2-hydroxybenzaldehydes towards Fe3+ and Ga3+ will be discussed. Different techniques, like UV-Vis, vibrational spectroscopy, and mass spectrometry were used for structural investigation of the complexes in solution and in the solid state. In this work the ESI MS and MS/MS spectra, including fragmentation pathways of Fe(III) and Ga(III) complexes with aroylhydrazones are presented. [1] T. Benković, A. Kenđel, J. Parlov-Vuković, D.
