Abstract
Tetrahedral [Zn(Amine)2I2] complexes which Amine = 3-methylpyridine (3-Mepy) (1), 4-methylpyridine (4-Mepy) (2), and N-methylimidazole (N-MeIm) (3) were synthesized and characterized by Fourier transform infrared, 1H NMR, and UV–vis spectroscopy. The crystal structures of 1–3 were determined by X-ray diffraction and have distorted tetrahedral geometry. The equilibrium formation constants and the molar absorptivity profiles of the complexes were obtained by multivariate hard modeling analysis of UV–vis absorption spectral data. Biological activities of the complexes were also studied on Staphylococcus aureus, Salmonella Typhi, Escherichia coli, and Bacillus subtilis by the well diffusion method.
