Synthese und Charakterisierung von [Zn{Si(NMe2)2(NHCMe3)(NCMe3)}‐(μ‐NC5H4)]2, einem molekularen Einkomponentenvorläufer zur Darstellung von ZnSiN2

Abstract: Für eine Verwendung als Einkomponentenvorläufer für die Darstellung von ZnSiN2 wurde aus dem zweifach lithiierten Aminosilan Si(NMe2)2(NLi t‐Butyl)2 und [ZnCl2(NC5H5)2] das Siladiazazinkacyclobutan [Zn{Si(NMe2)2(NHCMe3)(NCMe3)}(μ‐NC5H4)]2 erstmals dargestellt. Seine Kristallstruktur wurde am Einkristall gelöst (P1, a = 870.5(3) pm, b = 903.8(3) pm, c = 1530.6(4) pm, α = 96.982(5)°, β = 106.501(5)°, γ = 104.729(5)°). Die CP‐MAS‐NMR‐Daten für die Kerne 13C, 15N und 29Si werden mitgeteilt. Der Vorläuferkomplex wu… Show more

“…HRTEM images of the TiN and ZnSiN 2 nanoparticles clearly show pronounced lattice fringes that indicate the crystallinity of the as‐prepared nanoparticles (Figure 3b,e). The observed lattice distances of 2.1 Å (TiN) and 2.5 Å (ZnSiN 2 ) are well compatible with the bulk compounds ( d 200 of bulk‐TiN: 2.13 Å; d 002 of bulk‐ZnSiN 2 : 2.54 Å) [15d,16] . Fourier transformations of the HRTEM images confirm the crystallinity of the as‐prepared nanoparticles and are in accordance with the cubic lattice symmetry of NaCl‐type TiN (space group Fm‐3 m ) and the wurtzite‐type ZnSiN 2 (space group P6 3 mc ) (Figure 3c,f).…”

“…As an alternative, we have selected the molecular single‐source precursor [Zn{Si(NMe 2 ) 2 (NHCMe 3 )(NCMe 3 )}(μ‐NC 5 H 4 )] 2 , which was prepared following a recipe given by Jansen et al . ( SI: Figures S1,S2 ) [15d] . Thus, the single‐source precursor was heated in an autoclave for 1 h at 280 °C and resulted in a colorless suspension of ZnSiN 2 nanoparticles (Figure 1b).…”

“…33) and can be derived from the wurtzite structure type by ordering of tetrahedrally coordinated Zn 2+ and Si 4+ . This ordering can be verified by the first two superstructure reflections (110) and (011), which do not occur for ZnSiN 2 synthesized from molecular precursors , . The reflections of MT‐ZnSiN 2 are found to be fairly broad, indicating the small particle size of the resulting product pictorially highlighted by TEM.…”

“…Moreover, structurally defined 2-zincated pyridines are especially rare. [{Zn[Si(NMe 2 ) 2 (NHCMe 3 )(NCMe 3 )](μ-NC 5 H 4 )} 2 ] is the one previous example, which was made by an indirect metathetical approach and not by direct zincation, and also displays an uncapped (NCE) 2 (E=Zn) tricyclic arrangement [17]. Without the extra coordination provided by potassium caps, the (mean) Zn–C and Zn–N(pyr) bonds are predictably shorter (by 0.163 and 0.089 Å, respectively) in this neutral zinc complex compared with that in the ate example 4 .…”
