Isotype Strukturen einiger Hexaamminmetall(II)‐halogenide von 3d‐Metallen: [V(NH3)6]I2, [Cr(NH3)6]I2, [Mn(NH3)6]Cl2, [Fe(NH3)6]Cl2, [Fe(NH3)6]Br2, [Co(NH3)6]Br2 und [Ni(NH3)6]Cl2

Abstract: Durch Umsetzungen von VI2 und CrI2 mit flüssigem Ammoniak bei Raumtemperatur wurden gelbe Kristalle von [V(NH3)6]I2 bzw. grüne von [Cr(NH3)6]I2 erhalten. Farbloses [Mn(NH3)6]Cl2 wurde durch Umsetzung von Mn mit NH4Cl in überkritischem Ammoniak einkristallin dargestellt. Farblose und transparente Kristalle von [Fe(NH3)6]Cl2 und [Fe(NH3)6]Br2 konnten durch Umsetzung von FeCl2 bzw. FeBr2 in überkritischem Ammoniak bei 400°C erhalten werden. Wird unter den gleichen Bedingungen Tri‐μ‐amido‐bis[triammincobalt(III)]‐… Show more

“…For the capping nitrogen atoms N(4) and N(5) the Ca-N distances are significantly elongated to 2.675 (1) 6 ]X 2 (X = Cl and I) the M-N distances are 2.27 -2.28 Å [11].…”

“…The cationic complexes are located in the channels formed by the anionic strands (Figure 3). www.zaac.wiley-vch.de 2+ cations are in the typical range of 2.246(9)-2.31(1) Å, which is similar to other Mn II hexammine complexes. [35,42] The N-Mn-N angles amount to 81.8(4)-99.3(4)°and 163.0(3)-174.7(4)°indicating strong distortions of the coordination octahedron. These distortions are caused by Se···H-N hydrogen bridges between the hexammine complexes and the selenium atoms of the anions, which are attached to the complexes in a remarkable unsymmetrical fashion.…”

“…Due to the acidic conditions, a deprotonation of the ammine ligands does not occur. From the reaction of VI 2 with liquid ammonia, Jacobs and coworkers obtained [V(NH 3 ) 6 ]I 2 [7]. In order to complement these previous studies on the reactions of vanadium(III) halides with ammonia (liquid and gaseous), we now report our results on the reaction of VF 3 with liquid ammonia at -40 °C and at ambient temperature.…”
