摘要：

New homobinuclear Co(II), Ni(II), Cu(II), and Zn(II) complexes with Schiff base (H2L,1) have been synthesized and investigated using physicochemical techniques viz. IR, 1H NMR, 13C NMR, ESR, UV–Visible spectrometric methods, thermal gravimetric analysis, and magnetic moment measurements. The corrosion inhibition studies of the compounds on mild steel in (0.5 M) HCl have been investigated by weight loss, potential dynamics polarization, and scanning optical microscope. The adsorption of compounds was founded to obey the Langmuir adsorption isotherm model showing mixed type inhibition behavior. The in vitro antibacterial studies of the complexes against sulfate-reducing bacteria proved them as growth inhibiting agents. © 2015, Springer International Publishing AG.
