Abstract
Pripravljeni su koordinacijski polimeri mangana(II) i odabranih halogenih derivata nikotinske kiseline (2-bromnikotinska, 5-bromnikotinska i 6-klornikotinska kiselina) te 4,4'-bipiridina i 1,2-bis(4- piridil)etana. Manganov(II) klorid tetrahidrat korišten je kao metalna sol u sintezama, a voda, etanol i N,N'- dimetilformamid (DMF) korišteni su kao otapala u sintezama. Dobiveni produkti karakterizirani su IR spektroskopijom i termogravimetrijski (TGA), a maseni udio mangana(II) u produktima određen je UV/Vis spektrofotometrijski. Određene su molekulske formule dvaju koordinacijskih polimera {[Mn(2 − Brnic) 2 (4,4 ′ − bpy)(H 2 O) 2 ] · 2(4,4 ′ − bpy)} n (𝟏) i {[Mn (5 − Brnic) 2 (4,4 ′ − bpy)(H 2 O) 2 ] · 4,4 ′ − bpy · 2H 2 O} n (𝟐) . Pretpostavlja se da je manganov(II) ion oktaedarski koordiniran s dva O-monodentatno vezana nikotinatna liganda, dvije molekule vode te s dvije molekule 4,4'-bipiridina u molekulskim strukturama dobivenih polimera te da molekule 4,4'-bipiridina premošćuju manganove(II) ione pri čemu nastaju jednodimenzijski polimerni lanci. U kristalnim strukturama prisutne su kokristalizacijske molekule 4,4'-bipiridina (spoj 1) odnosno 4,4'-bipiridina i vode (spoj 2).
Abstract (english)
Coordination polymers of manganese(II) and selected nicotinic acid haloderivatives (2- bromonicotinic, 5-bromonicotinic and 6-chloronicotinic acid) and 4,4'-bipyridine and 1,2-bis(4- pyridyl)ethane were prepared. Manganese(II) chloride tetrahydrate was used as the metal salt, whilst water, ethanol, and N, N'- dimethylformamide (DMF) were used as solvents in the syntheses. The obtained products were characterized by IR spectroscopy and thermogravimetric analysis (TGA). The mass fractions of manganese(II) in the prepared compounds were determined by UV/Vis spectrophotometry. The molecular formulae of two coordination polymers were determined as {[Mn(2 − Brnic) 2 (4,4 ′ − bpy)(H 2 O) 2 ] · 2(4,4 ′ − bpy)} n (𝟏) and {[Mn (5 − Brnic) 2 (4,4 ′ − bpy)(H 2 O) 2 ] · 4,4 ′ − bpy · 2H 2 O} n (𝟐) . It is proposed that the manganese(II) ion is octahedrally coordinated with two O-monodentate nicotinate ligands, two water molecules and with two 4,4’- bipyridine molecules in the molecular structures of the obtained polymers. The 4,4'-bipyridine molecules bridge the manganese(II) ions leading to the formation of one-dimensional polymeric chains. There are 4,4'-bipyridine molecules of crystallization in the crystal structure of compound 1 and 4,4'-bipyridine and water molecules of crystallization in the crystal structure of compound 2.
