Abstract
Po že znanih sinteznih poteh smo pripravili dve koordinacijski spojini cinka(II) z amonijakom, [Zn(NH3)4](BF4)2 in [Zn(NH3)4](PF6)2. Pri reakcijah iona [Zn(NH3)4]2+ v vodni raztopini amonijaka s kinaldinsko kislino je izkristalizirala spojina, ki je vsebovala tako koordiniran kinaldinat kot amonijak, [Zn(quin)2(NH3)]. Pri reakcijah [Zn(NH3)4]2+ v vodni raztopini amonijaka s pikolinsko kislino je izkristalizirala že znana spojina s koordiniranim pikolinatom in vodo, [Zn(pic)2(H2O)3)]∙2H2O, pri reakcijah s pirazinojsko kislino pa zmes [Zn(pyraz)2(H2O)2] in [Zn(pyraz)2(H2O)]. Izbrane komplekse z amonijakom smo reagirali pri sobnih pogojih z acetonitrilom. Le v primeru [Zn(quin)2(NH3)] je bila potrjena reakcija amonijaka z acetonitrilom. Pri tej reakciji je nastal acetamidin

Preparation and reactions of selected zinc(II) ammino complexes |
Secondary abstract: |
Following the known synthetic procedures, two zinc(II) ammine coordination compounds, [Zn(NH3)4](BF4)2 and [Zn(NH3)4](PF6)2, were prepared. Reactions of [Zn(NH3)4]2+ with quinaldinic acid in aqueous ammonia has afforded [Zn(quin)2(NH3)], a compound that contains coordinated quinaldinate and ammonia. Analogous reactions of [Zn(NH3)4]2+ with picolinic acid have afforded an already known [Zn(pic)2(H2O)3)]∙2H2O, a complex with coordinated picolinate and water. Similar reaction with pyrazinoic acid has produced a mixture of [Zn(pyraz)2(H2O)2] and [Zn(pyraz)2(H2O)]. Selected ammine complexes have been reacted with acetonitrile at ambient conditions. Only in the case of [Zn(quin)2(NH3)], a reaction of ammonia with acetonitrile has been undoubtely confirmed. The latter reaction produces acetamidine. |
