20.500.12556/DKUM-67759 Two new zinc(II) acetates with 3- and 4-aminopyridine syntheses and structural properties 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. zinc(II) acetate dihydrate aminopyridine x-ray crystal structure hydrogen bonds koordinacijske spojine cink aminopiridin vodikove vezi struktura rentgenska strukturna analiza true true true Angleški jezik Slovenski jezik Članek v reviji 2017-08-30 09:01:39 2017-08-30 09:02:41 2024-03-08 08:03:35 2019-07-11 16:30:29 2015 0 0 str. 312-318 št. 2 Letn. 62 2015 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1318-0207 546.47:547.82 14086149 1536350147 10.17344/acsi.2014.1111 1318-0207 URN:SI:UM:DK:72RRPCZP Acta_Chimica_Slovenica_2015_Dojer_et_al._Two_new_zinc(II)_acetates_with_3–_and_4–aminopyridine_syntheses_and_structural_properties.pdf Acta_Chimica_Slovenica_2015_Dojer_et_al._Two_new_zinc(II)_acetates_with_3–_and_4–aminopyridine_syntheses_and_structural_properties.pdf 1 199B2781D152364626CE89E102A1271C a54da9e175efb2d308e98d6c0797d3e2a9dcbe5274646c20971925cd0f1818e3 953c6b88-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/8cd9754e-08a7-48c0-aec8-3a0cea5ebf98 https://dk.um.si/Dokument.php?lang=slv&id=116390 https://journals.matheo.si/index.php/ACSi/article/view/1111 1 https://dk.um.si/Dokument.php?lang=slv&id=116389 Fakulteta za naravoslovje in matematiko 0 0 0
