Abstract
Abstract Three new aroylhydrazones including a triazole ring, 2-phenyl-1,2,3-triazolyl-4-carbaldehyde benzoylhydrazone (HL 1 ), 2-phenyl-1,2,3-triazolyl-4-carbaldehyde isonicotinylhydrazone (HL 2 ) and 2-phenyl-1,2,3-triazolyl-4-carbaldehyde salicyloylhydrazone (HL 3 ) and their chelates with some transition metal have been synthesized and studied using X-ray photoelectron spectroscopy (XPS). The XPS spectra show that the 2 p electron binding energy (B.E.) of the metal ions (M 2 p ) and the 1 s electron of nitrogen atom coordinated are decreased and the 1 s electron of coordinating oxygen atom is increased after coordination. During coordination, the direction of electron transfer is from the ligand to the metal ion (L → M) and the coordination bonds formed are both of σ-type and π-type.
