Sinteza kompleksa nikljevega(II) nitrata s piridin-2-onom

Andrejčič, Tina (author), Petriček, Saša (mentor)

Po reakciji med Ni(NO3)2.6H2O in piridin-2-onom, C5H5NO, v etanolu ali metanolu pri sobni temperaturi nastane raztopina, iz katere se med odhlapevanjem topila izločijo zeleni kristali nove spojine [Ni(C5H5NO)4(H2O)2](NO3)2. Po reakciji med Ni(NO3)2.6H2O in piridin-2-onom v acetonitrilu pri sobni temperaturi nastane suspenzija. Oborino [Ni(C5H5NO)4(H2O)2](NO3)2 smo odfiltrirali in posušili v eksikatorju. Sestavo in strukturo kristalov in oborine smo potrdili z rentgensko strukturno analizo, IR spektroskopijo, CHN in termično analizo.

Abstract

A reaction of Ni(NO3)2.6H2O with pyridine-2-one, C5H5NO, in ethanol or methanol at room temperature resulted in a solution from which by solvent evaporation green crystals of a new compound [Ni(C5H5NO)4(H2O)2](NO3)2 were obtained. Reaction of Ni(NO3)2.6H2O and pyridine-2-one in acetonitrile at room temperature resulted in a suspension. The precipitate, [Ni(C5H5NO)4(H2O)2](NO3)2, was filtered off and dried in an exicator. The composition and structure of crystals and precipitate were investigated using X-ray, structure analysis, IR spectroscopy, CHN and thermal analysis.
