Abstract

Sintetizirala sem tri bakrove(II) spojine z anionom 5-sulfosalicilne kisline (= H3L = C7H6O6S) in piridinamidom (apy) v vodi. Uporabila sem tri različne piridinamide z amidno skupino na mestih 4, 3 ali 2 piridinskega obroča. Spojini {[Cu(HL)(4-apy)(H2O)2] 2H2O}n je že bila določena struktura. Ugotovila sem, da se praškovni difraktogram spojine 1 ujema z izračunanim difraktogramom te znane spojine. Za spojini 2 in 3 takšnega ujemanja nisem našla, oziroma v tem sistemu nisem našla druge znane spojine. Glede na elementno analizo za spojino 2 sklepam na formulo Cu(HL)(2-apy)(H2O)3, za spojino 3 pa na formulo Cu(HL)(3-apy)2(H2O)3. IR spektri spojin 1-3 so si podobni, kar se sklada s predlaganimi formulami in tako z enakimi ali skoraj enakimi ligandi. Absorbirana rdeča svetloba spojin 1-3, ki se vidi v UV-Vis spektrih, se sklada s komplementarno zeleno barvo treh izoliranih spojin.

Secondary title: Copper(II) compounds with 5-sulfosalicylic acid and pyridineamide derivatives
Secondary abstract: Three copper(II) compounds were synthesized with an anion of 5-sulfosalicylic acid (=H3L= C7H6O6S) and pyridinamide (apy) in water. Three different pyridineamides with the amide group at positions 4, 3 or 2 of the pyridine ring were applied. The structure of the compound {[Cu(HL)(4-apy)(H2O)2]ּ 2H2O}n has already been determined. The powder diffractogram of compound 1 matches the calculated diffractogram of this known compound. On the other hand, no such mathes for the compounds 2 and 3, neither any another known compound in this system was found. According to the elemental analysis, formula Cu(HL)(2-apy)(H2O3) is assigned to the compound 2, while Cu(HL)(3-apy)ּ2 2H2O to the compound 3. The IR spectra of the compounds 1-3 are very similar, all in agreement with the proposed formulae and thus with the same or almost identical ligands, The absorbed red light of the compounds 1-3, seen in the UV-Vis spectra, is consistent with the complementary green color of the three isolated compounds.
