The solution behavior of dopamine in the presence of mono and divalent cations: A thermodynamic investigation in different experimental conditions

2021

The interactions of dopamine [2-(3,4-Dihydroxyphenyl)ethylamine, (Dop-)] with methylmercury(II) (CH3Hg+), magnesium(II), calcium(II), and tin(II) were studied in NaCl(aq) at different ionic strengths and temperatures. Different speciation models were obtained, mainly characterized by mononuclear species. Only for Sn2+ we observed the formation of binuclear complexes (M2L2 and M2LOH (charge omitted for simplicity)

Study of [2-(2’-pyridyl)imidazole] complexes to confirm two main characteristic thermoanalytical behaviors of transition metal complexes based on imi…

2016

Abstract Imidazole derivative ligands are recognized as useful models for biomimetic complexes. Among the inorganic–organic hybrid complexes, those with derivatives of imidazole heterocyclic N-donor ligands are interesting for their framework. In previous studies of complexes with imidazole derivative ligands, our group reported two main thermally induced decomposition behaviors supporting two different systematic decomposition trends. In this work, one of these characteristic decomposition mechanisms was again found. The final goal of these serial studies is the possibility to provide, by the experimental evidences, a prediction model of thermal stability and decomposition typical behavior…
