Sinteza in karakterizacija spojin železovega sulfata z aminopiridini : magistrsko delo
Gorenjak, Sara
Namen magistrskega dela je sinteza spojin železa z aminopiridini. Uporabili smo železov(II) sulfat(VI) in različne aminopiridine (2-aminopiridin, 3-aminopiridin in 4-aminopiridin). Opravljenih je ...bilo 24 sintez. Sinteze smo izvedli na tri načine, in sicer z mešanjem pri sobni temperaturi, pod refluksom in solvotermalno sintezo. Kot topili sta bila v večini primerov uporabljena metanol in N,N-dimetilformamid. Sintezni produkti so bili karakterizirani z infrardečo spektroskopijo in rentgensko analizo na monokristalu. Sintetizirali smo že dve znani in objavljeni spojini, bis(2-aminopiridin) sulfat ter bis(4-aminopiridin) sulfat monohidrat. Uspelo nam je sintetizirati tudi novo spojino, katere struktura še ni objavljena, kristalohidrat 3-aminopiridinijev sulfat, ▫$6C5H7N2+ 3SO42- 3H2O$▫. Snov ima veliko asimetrično enoto, ki vsebuje šest 3-aminopiridinijevih kationov, tri sulfatne ione in tri molekule vode. Veliko število vodikovih vezi vpliva na asimetrično strukturo. Spojina kristalizira v triklinskem kristalnem sistemu.
