Bakrove(II) spojine z anionom 2-metilbenzojske kisline

Hren, Anja (author), Kozlevčar, Bojan (mentor)

Sintetizirala sem štiri bakrove(II) koordinacijske spojine z anionom 2-metilbenzojske kisline (= HL). To so Cu(L)2(H2O)2 1, Cu(L)(C2H3O2)(H2O) 2, Cu(L)2(C6H6N2O)2(H2O)2 3 in Cu2(L)4(C5H6N2)(H2O) 4. Kot topilo sem uporabila destilirano vodo. Bakrovim izhodnim spojinam sem dodajala 2-metilbenzojsko kislino, ki se na bakrov(II) ion veže kot anion. Poleg tega sem uporabljala tudi nevtralni ligand nikotinamid (C6H6N2O) in 2-aminopiridin (C5H6N2). Za vsako spojino sem pripravila tri enake sinteze, saj smo tako lahko sklepali, da je sinteza ponovljiva. Z rentgensko praškovno analizo smo primerjali difraktograme, iz katerih smo potrdili, da smo dobili iste koordinacijske spojine. S pomočjo CHN elementne analize smo ugotovili formule teh spojin.

• Title: Copper(II) compounds with 2-methylbenzoic acid anion

Abstract

Four copper(II) coordination compounds with 2-methylbenzoic acid (= HL) anion have been synthesized. These are Cu(L)2(H2O)2 1, Cu(L)(C2H3O2)(H2O) 2, Cu(L)2(C6H6N2O)2(H2O)2 3 and Cu2(L)4(C5H6N2)(H2O) 4. Distilled water was used as a solvent. 2-Methylbenzoic acid, being added to the starting copper compounds, is bonded to the copper(II) ion as an anion. Neutral ligands nicotinamide (C6H6N2O) and 2 aminopyridine (C5H6N2) were added additionally. Each synthesis was proceeded tree times to deduce their reproducibility. The X-ray powder diffraction analysis was applied to confirm the identity of synthesized coordination compounds. Formulae of the synthesized compounds were determined with the CHN elemental analysis.
