Synthesis and characterization of novel Hg(II) complexes with new Schiff bases

Abstract

The research included the use of new Schiff’s bases to prepare novel mercury (II) complexes as follows: Schiff’s bases ligands prepared using aromatic aldehydes and various aromatic primary amines [S1-S6]. Six mercury complexes [H1-H6] were prepared by the interaction of mild moles of organic Schiff’s bases with 1 mol of mercury salt (CH3COO)2Hg. The Schiff’s bases prepared spectroscopes were diagnosed by the UV–visible spectrum, the infrared spectrum (FT-IR), and the nuclear magnetic resonance spectrum ( 1 H NMR). The reaction mechanism was proposed in light of these results, as it confirmed the validity of the proposed chemical compositions. Metallic complexes prepared spectrally were diagnosed by the UV–visible spectrum, the infrared spectrum and the mass spectrum (Lc-Mass), and analysis of the ele ments C.H.N.S. The mechanism of interaction was suggested in light of these results, as it confirmed the validity of the proposed chemical compositions, magnetic and electrical conductivity sensitivity of all the prepared complexes was measured. Lc-Mass spectrum results, analysis of the elements C.H.N.S, measurement of molar conductivity, magnetic moment measurements have proven that azomethine compounds interacting with cadmium chloride and mercury acetate are di ligand. 2021 Elsevier Ltd.
