Abstract

Graphical abstract: Five novel d-electron complexes with pyridinecarboxamides were obtained and characterized. The position of nitrogen atom in the pyridine ring of the ligand plays a significant role in crystal structure determination. Complexes with Cu(II), Ni(II) and Co(II) ions revealed an antifungal activity against Fusarium culmorum pathogen. Abstract: Five novel complexes of d-electron metal ions with picolinic and isonicotinic acid amide derivatives were obtained. All products were characterized in detail with the use of elemental, thermogravimetric, X-ray diffraction, FT-IR and EPR spectra analysis. The chloride, nitrate or acetate salts of Cu(II), Zn(II), Co(II) and Ni(II) were used to the synthesis with carboxamide ligands resulting in five new crystalline compounds. Selected compounds were also used for antifungal activity examination against Fusarium culmorum pathogen. This examination was conducted using two different methods: the inhibition zone measurements and visual observation of retardation influence on fungi spores growth.
