diplomsko delo
Povzetek
V okviru diplomskega dela smo pripravili vodno raztopino iona [Zn(NH3)4]2+. V vodni raztopini amoniaka smo raztopili cinkov oksid in dodali različne kisline: kinaldinsko, pikolinsko ali pirazinojsko kislino.
V vseh primerih se je na cinkov(II) ion koordiniral anion uporabljene kisline (kinaldinat, pikolinat ali pirazinoat). Le v primeru kinaldinata je na cinkov(II) ion ostala koordinirana ena molekula amoniaka. Tako so bile pripravljene naslednje koordinacijske spojine cinka(II): [Zn(quin)2(NH3)], [Zn(pic)2(H2O)2]·2H2O, [Zn(pyra)2(H2O)2] in [Zn(pyra)2(H2O)]n.
Na analogen način smo pripravili vodno raztopino z ionom [Cu(NH3)4]2+ in to reagirali z istimi kislinami. Tako so bile pripravljene naslednje koordinacijske spojine bakra(II): [Cu(quin)2(H2O)], [Cu(pic)2]n·2nH2O in [Cu(pyra)2]n.

Syntheses of coordination compounds of zinc(II) or copper(II) from aqueous ammonia solution |
Sekundarni povzetek: |
An aqueous solution of [Zn(NH3)4]2+ was prepared within this diploma work. The solution was prepared by dissolving zinc(II) oxide in aqueous ammonia solution. Different acids were added to this solution: quinaldinic acid, picolinic acid or pyrazinoic acid. In all cases, the anionic forms of the used acids, i.e., quinaldinate, picolinate or pyrazinoate, coordinated to zinc(II). In the case of quinaldinate reaction system, one molecule of ammonia remained coordinated to zinc(II). Thereby we isolated the following zinc(II) coordination compounds: [Zn(quin)2(NH3)], [Zn(pic)2(H2O)2]·2H2O, [Zn(pyra)2(H2O)2] and [Zn(pyra)2(H2O)]n.
By analogy, an aqueous solution of the [Cu(NH3)4]2+ ion was prepared and reacted with the same acids. Thereby the following copper(II) coordination compounds were prepared: [Cu(quin)2(H2O)], [Cu(pic)2]n·2nH2O and [Cu(pyra)2]n. |
