| Abstract: | Two dimeric copper(II) complexes of the biologically important compound l-carnitine were isolated from ethanolic and aqueous solutions with formulas [Cu2(l-carnitine)2Cl2(H2O)2] · Cl2 (complex 1) and [Cu2(l-carnitine)4(H2O)2] · (ClO4)4 · H2O · CH2Cl2 (complex 2), respectively. Complex 1 was characterized in solid state by elemental analysis, thermal analysis (TG, DTG), IR and EPR as well as in solution with cationic and anionic ESMS, EPR, NMR and UV–Vis spectroscopies. For complex 2, crystals were isolated after recrystallization and characterized by X-ray crystallography, elemental analysis, IR and NMR spectroscopies. |
