•Six new complexes of Cthta were synthesized and characterized.•The complexes were characterized by using spectroscopic methods.•The antimicrobial activities of Cthta and its metal complexes were evaluated.
2-Cyano-2-(p-tolyl-hydrazono)-thioacetamide (Cthta) reacted with V(IV), Zr(IV), Pd(II), Pt(IV), Ce(IV) and U(VI) in acetone as a solvent at room temperature to form a solid complexes with characteristic color for metal ion. The molar ratio for all synthesized complexes is M:Cthta = 1:2 which was established from the results of chemical analysis. The isolated complexes have been characterized with their melting points, elemental analysis, magnetic properties, conductance measurements, mass, IR, UV–Vis. and 1H NMR spectroscopic methods and thermal analyses. The results supported the formation of the complexes and indicated that the Cthta reacts as a bidentate ligand. The thermogravimetric and infrared spectroscopic data confirmed the presence of water in the composition of the complexes. The molar conductance values of all complexes in (DMSO) were found in the range 150.71–328.85 S cm2 mol−1 at room temperature. The magnetic moments of the complexes were measured at room temperature. The kinetic parameters of thermogravimetric and its differential have been evaluated by using Coats Redfern (CR) and Horowitz–Metzeger (HM) methods. The ligand as well as their metal complexes were also evaluated for their antibacterial and antifungal activities.
Graphical abstractThe synthesis, the characterization and the antibacterial activity of the neutral mononuclear V(IV), Zr(IV), Pd(II), Pt(IV), Ce(IV) and U(VI) complexes with the 2-Cyano-2-(p-tolyl-hydrazono)-thioacetamide (Cthta) are presented.Figure optionsDownload full-size imageDownload as PowerPoint slide
