Ein zweikerniger Nickel(I)‐Distickstoffkomplex und seine Reduktion in Einelektronenschritten

Abstract: Elektron für Elektron: β‐Diketiminatonickel(I)‐Komplexfragmente sind dazu in der Lage, Distickstoff durch Koordination zu aktivieren. Der entstehende Komplex kann in zwei Einelektronenschritten reduziert werden, wodurch die N‐N‐Bindung weiter aktiviert wird. Das Bild zeigt die Molekülstruktur des einfach reduzierten Komplexes mit μ‐η1:η1‐gebundenem N2.magnified image

“…[1,[3][4][5] The conversion of SF 6 in the coordination sphere of transition metals has to date only been described by Ernst and co-workers: Low-valent complexes were reacted with SF 6 to give mixtures of different metal fluorides. [7] Herein, we show that the same nickel compounds are even capable of converting SF 6 under standard ambient conditions. [6] In previous studies, we have evaluated the behavior of low-coordinate b-diketiminate nickel complexes [(L tBu Ni I ) 2 (m-h 1 :h 1 -N 2 )] (I) and K 2 [(L tBu Ni I ) 2 (m-h 1 :h 1 -N 2 2À )] (II; Scheme 1) towards small molecules.…”

[18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36] We have been able to extend the range of diazenide composition through a novel synthetic approach employing controlled thermal decomposition of ionic azides in a multianvil device under high-pressure/high-temperature (HP/HT) conditions. [37] We thereby obtained calcium diazenide CaN 2 , which is isotypic with SrN 2 and alkaline earth acetylenides crystallizing in a tetragonally distorted NaCl-type structure.…”

“…Der zwischen den Nickel(I)‐Metallzentren end‐on gebundene verbrückende Stickstoff weist eine N‐N‐Bindungslänge von 1,120(4) Å auf (Abbildung 9). Die ebenfalls mögliche Bildung von einfach und zweifach reduzierten strukturell verwandten Komplexen weitet die N‐N‐Bindung von 1,143(8) Å zu 1,185(8) Å auf 3_11…”
