syntheses and structural properties
Abstract
The synthesis and characterization of two new zinc(II) coordination compounds with 3- and 4-aminopyridine are reported. They were obtained after adding a water solution of $Zn(CH_3COO)_2$ · $2H_2O$ or dissolving solid $Zn(CH_3COO)_2$ · $2H_2O$ in methanol solutions of 3- and 4-aminopyridine. The products were characterized structurally by single-crystal X-ray diffraction analysis. Colourless crystals of the compound synthesized by the reaction of $Zn(CH_3COO)_2$ · $2H_2O$ and 3-aminopyridine (3-apy), are built of trinuclear complex molecules with the formula $[Zn_3(O_2CCH_3)_6(3- apy)_2(H_2O)_2]$(1). The molecules consists of two terminal $Zn$ atoms, coordinated tetrahedrally, and one central $Zn$ atom, coordinated octahedrally. Colourless crystals, obtained by the reaction of $Zn(CH_3COO)_2$ · $2H_2O$ with 4-aminopyridine (4-apy), consist of a mononuclear complex $[Zn(O_2CCH_3)_2(4-apy)_2]$(2). Hydrogen-bonding interactions in the crystal structures of both complexes are reported.

Sintetizirali in karakterizirali smo novi cinkovi koordinacijski spojini s 3- in 4-aminopiridinom. Dobili smo ju z dodajanjem metanolne raztopine $Zn(CH_3COO)_2$ · $2H_2O$ v vodno raztopino 3-aminopiridina oziroma raztapljanjem $Zn(CH_3COO)_2$ · $2H_2O$ v metanolni raztopini 4-aminopiridina. Produkta sta bila okarakterizirana z rentgensko strukturno analizo monokristalov. Brezbarvni kristali, pridobljeni z reakcijo med $Zn(CH_3COO)_2$ · $2H_2O$ in 3-aminopiridinom, so zgrajeni iz trijedrnih koordinacijskih molekul s kemijsko formulo $[Zn_3(O_2CCH_3)_6(3-apy)_2(H_2O)_2]$(1). Molekula je sestavljena iz dveh terminalnih cinkovih ionov, ki sta tetraedično koordinirana, in enega centralnega iona, ki je oktaedrično koordiniran. Brezbarvni kristali, dobljeni z reakcijo med $Zn(CH_3COO)_2$ · $2H2_O$ in 4-aminopiridinom, sestojijo iz enojedrnih koordinacijskih molekul s kemijsko formulo $[Zn(O_2CCH_3)_2(4-apy)_2]$(2). Poročamo tudi o vodikovih vezeh v kristalnih strukturah obeh spojin. |
