Materials decay naturally through a process called corrosion in which they react with their surroundings. It is possible to prevent mild steel from corroding in hydrochloric acid (HCl) by applying a variety of corrosion inhibitors. In this work, the novel mononuclear manganese coordination complex [Mn(Hbpz)₂(NCS)₂] showed promising properties that make it suitable for corrosion prevention applications. In this experiment, different experimental methods were used to evaluate its inhibitory potential. For example, weight loss (WL) showed a 96% reduction in corrosion rate at higher concentrations. EIS was evidence that the concentration effect increases R_ct and reduces C_dl. Moreover, the polarization examination demonstrated that C3 is a mixed-type inhibitor. In addition, quantum mechanical and statistical methods were also used, and the effect of temperature was also determined. Besides, thermodynamic equations were used and calculated. The adsorption follows the Langmuir isothermal model and the simulation method confirmed the spontaneous adsorption nature of the complex, which improves the surface characterization results.
