Bakrove in cinkove spojine s 4-aminobenzojsko kislino

Rode, Tajda (author), Kozlevčar, Bojan (mentor)

Opisala sem tri cinkove(II) in eno bakrovo(II) koordinacijsko spojino z anionom 4-aminobenzojske kisline (HL). Te spojine so [CuCl2(HL)2] 1, [ZnCl2(HL)2] 2, {[Zn(L)2(H2O)](H2O)}n 3 in [Zn(L)(N3)]n 4. Pri spojinah 1 in 2, ki sta enojedrni, se naslovna kislina, kot ligand, veže nevtralno preko dušikovega atoma, pri spojinah 3 in 4, ki sta večjedrni, pa potekajo koordinacije preko dušikovega in kisikovega atoma anionskega L in pri 4 tudi dodatno preko azidnih anionov. Osnovne formulske enote so povezane tudi z vodikovimi vezmi. Z elementno CHN analizo se ugotavljata delež določenega elementa in s tem skladnost s formulo, dobljeno iz določene strukture. Primerjala sem tudi objavljene podatke za IR in elektronsko spektroskopijo, ki se skladajo s prisotnimi ligandi (IR) in podobnostjo v koordinacijski sferi (UV-Vis).

• Title: Copper and zinc compounds with 4-aminobenzoic acid

Abstract

Three zinc(II) and one copper(II) coordination compounds with 4-aminobenzoic acid (HL) have been described. These compounds are [CuCl2(HL)2] 1, [ZnCl2(HL)2] 2, {[Zn(L)2(H2O)](H2O)}n 3 and [Zn(L)(N3)]n 4. For the mononuclear compounds 1 and 2, the title acid, as the ligand, binds neutrally via the nitrogen atom. On the other hand, in the case of the polynuclear compounds 3 and 4 coordination takes place via the nitrogen and oxygen atom of the anionic L, and additionally via the azide anions for 4. The basic formula units are also linked by the hydrogen bonds. Elemental CHN analysis was used to check the proportion of a particular element and thus compliance with the formula obtained from a specific structure. Furthermore, the IR and electron spectroscopy data were compared and all are in agreement with the present ligands (IR) and similarities within coordination spheres (UV-Vis).
