Abstract
Pripravljeni su koordinacijski polimeri kobaltovog(II) iona s miješanim ligandima: derivatima nikotinske kiseline (2-bromnikotinska kiselina ili 2-klornikotinska kiselina) te 1,2-bis(4-piridil)etanom ili 1,2-bis(4- piridil)etenom. Kao metalna sol korišten je kobaltov(II) nitrat heksahidrat, a kao otapala korišteni su DMF i voda. Spojevi su karakterizirani IR spektroskopijom, UV-Vis-NIR spektroskopijom termogravimetrijskom analizom (TGA), diferencijalnom skenirajućom kalorimetrijom (DSC) te cikličkom voltametrijom. Dobiveni su koordinacijski polimeri molekulskih formula: [Co(2-Cl-nic) 2 (1,2-bpeten)] n , [Co(2-Br-nic) 2 (1,2-bpeten)] n , [Co(2- Cl-nic) 2 (1,2-bpetan)] n. Kobaltov(II) ion oktaedarski je koordiniran s četiri O donirajuća liganda (karboksilatni kisici derivata nikotinske kiseline i/ili vode) i s dva piridinska dušikova atoma. Molekule 1,2-bis(4-piridil)etana i 1,2-bis(4-piridil)etena premošćuju kobaltove(II) ione dajući beskonačni jednodimenzijski polimerni lanac.
Abstract (english)
Coordination polymers of cobalt(II) ion with mixed ligands: nicotinic acid derivatives (2- bromonicotinic acid or 2-chloronicotinic acid) and 1,2-bis(4-pyridyl)ethane or 1,2-bis(4-pyridyl)ethene were prepared. Cobalt(II) nitrate hexahydrate was used as the metal salt, and DMF and water were used as the solvent. The compounds were characterized by IR spectroscopy, UV-Vis-NIR spectroscopy, thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and cyclic voltammetry. Coordination polymers of molecular formulae were obtained: [Co(2-Cl-nic) 2 (1,2-bpetene)]n, [Co(2-Br-nic) 2 (1,2-bpetene)] n , [Co(2-Cl-nic) 2 (1,2- butane)] n . The cobalt(II) ion is octahedrally coordinated with four donating O ligand (carboxylate oxygens of nicotinic acid derivatives and/or water and with two pyridine nitrogen atoms. Molecules of 1,2-bis(4-pyridyl)ethane and 1,2- bis(4-pyridyl)ethene bridge cobalt(II) ions to give an infinite one-dimensional polymer chain.
