How covalence breaks adsorption-energy scaling relations and solvation restores them.
Calle-Vallejo F, Krabbe A, García-Lastra JM. Calle-Vallejo F, et al. Chem Sci. 2017 Jan 1;8(1):124-130. doi: 10.1039/c6sc02123a. Epub 2016 Aug 5. Chem Sci. 2017. PMID: 28451156 Free PMC article.
Taking metalloporphyrins as a case study, we evaluate here the adsorption energies of those adsorbates on the metal centers Cr, Mn, Fe, Co, Ni and Cu, using H, F, OH, NH(2), CH(3), and BH(2) as ring ligands. We show that covalence systematically breaks scaling relations un …
