“…For example, the introduction of ligands such as β-diketonate, acetylacetone, and triphenylphosphane (PPh 3 ) can result in remarkable differences in the structures of metal complexes with BTAH, specifically, the transformation of single metal nuclear to multinuclear complexes. [1,[44][45][46][47][48][49] Therefore, it is worth investigating the inhibition of BTAH in nonaqueous solutions containing some organic molecules that might play an important role in the formation of surface complex films. In contrast, it is highly desirable to extend SERS studies directly to wider applications in surface science, not only for the various processes of corrosion and inhibition, but also for the surface coordination chemistry of BTAH together with other ligands.…”
