Abstract
Pripravljeni su koordinacijski polimeri kobaltovog(II) iona s miješanim ligandima - derivatima nikotinske kiseline (6-bromnikotinska kiselina (6-BrnicH) i 6-klornikotinska kiselina (6-ClnicH)) te bispiridilnim ligandima 1,2-bis(4-piridil)etanom (1,2-bpetan) i 1,2-bis(4-piridil)etenom (1,2-bpeten). Kao otapalo korišten je N,N-dimetilformamid, DMF. Dobiveni su koordinacijski polimeri: [Co(6- BrnicH) 2 (1,2-bpetan)] n , [Co(6-BrnicH) 2 (1,2-bpeten)] n i [Co(6-ClnicH) 2 (1,2-bpeten)] n . U [Co(6-BrnicH) 2 (1,2-bpetan)] n , kobaltov(II) ion je oktaedarski koordiniran s O1 i O2 atomima karboksilata iz O,O`-kelatirajućeg 6-bromnikotinatnog liganda, s O3 i O4 atomima iz dva različita O,O`- premošćujuća 6-bromnikotinatna liganda te s piridinskim N3 i N4 atomima iz dvije različite molekule 1,2- bis(4-piridil)etana. U [Co(6-BrnicH) 2 (1,2-bpeten)] n , kobaltov(II) ion je oktaedarski koordiniran s O3 i O4 atomima karboksilata iz O,O`-kelatirajućeg 6-bromnikotinatnog liganda, s O1 i O2 atomima iz dva različita O,O`-premošćujuća 6-bromnikotintna liganda te s piridinskim N3 i N4 atomima iz dvije različite molekule 1,2-bis(4-pirdil)etena. U [Co(6-ClnicH) 2 (1,2-bpeten)] n , kobaltov(II) ion je oktaedarski koordiniran s O3 i O4 atomima karboksilata iz O,O`-kelatirajućeg 6-klornikotinatnog liganda, s O1 i O2 atomima iz dva različita O,O`-premošćujuća 6-klornikotinatna liganda te s piridinskim N3 i N4 atomima iz dvije različite molekule 1,2-bis(4-piridil)etena. Molekule 1,2-bpetana i 1,2-bpetena premošćuju kobaltove(II) ione dajući beskonačni jednodimenzijski polimerni lanac. Spojevi su karakterizirani IR spektroskopijom, termogravimetrijskom analizom (TGA) te diferencijalnom pretražnom kalorimetrijom (DSC). Kristalne strukture navedenih spojeva određene su metodom difrakcije rentgenskog zračenja na monokristalu.
Abstract (english)
Cobalt(II) coordination polymers with nicotinic acid derivates (6-bromonicotinic (6-BrnicH) and 6- chloronicotinic acid (6-ClnicH)) and 1,2-bis(4-pyridyl)ethane (1,2-bpethane) and 1,2-bis(4-pyridyl)ethene (1,2-bpethene) were prepared. The solvent used was N,N-dimethylformamide, DMF. The obtained coordination polymers were [Co(6-BrnicH) 2 (1,2-bpethane)] n , [Co(6-BrnicH) 2 (1,2-bpethene)] n and [Co(6-ClnicH) 2 (1,2-bpethene)] n . In [Co(6-Br-nicH) 2 (1,2-bpethane)] n , the cobalt(II) ion is octahedrally coordinated by O1 and O2 carboxylate atoms of the O,O'-chelating 6-bromonicotinate ligand, by O3 and O4 atoms from two different O,O'-bridging 6-bromonicotinate ligand and by pyridine N3 and N4 atoms from two different molecules of 1,2-bis(4-pyridil)ethane. In [Co(6-BrnicH) 2 (1,2-bpethene)] n , the cobalt(II) ion is octahedrally coordinated by O3 and O4 carboxylate atoms of the O,O'-chelating 6-bromonicotinate ligand, by O1 and O2 atoms from two different O,O-bridging 6-bromonicotinate ligand and by pyridine N3 and N4 atoms from two different molecules of 1,2-bis(4-pyridil)ethene. In [Co(6-ClnicH) 2 (1,2-bpethene)] n , the cobalt(II) ion is octahedrally coordinated by O3 and O4 carboxylate atoms of the O,O'-chelating 6-chloronicotinate ligand, by O1 and O2 atoms from two different O,O'-bridging 6-chloronicotinate ligand and by pyridine N3 and N4 atoms from two different molecules of 1,2-bis(4-pyridil)ethene. The bridging 1,2-bpethane and 1,2-bpethene ligands connect cobalt(II) ions into infinite one-dimensional polymeric chains. The compounds were characterized by IR spectroscopy, thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The crystal structures of these compounds were determined by the single-crystal X-ray structural analysis.
