“…Die 29 Si-NMR-chemischen Verschiebungen, die Wellenzahlen der ν(SiϪH)-Banden und die 1 H-NMR-chemischen Verschiebungen des Wasserstoffatoms der SiϪH-Gruppe von 1c-Li, 1a-NaϪ1d-Na und 1a-KϪ1d-K sind in der Tabelle 1 angegeben. [17] 1c-Li wurde entsprechend den Angaben in [4] durch Reaktion von 13 mmol Me 2 (H)SiϪNHϪSi(H)Me 2 , gelöst in 50 ml n-Pentan, mit der äquimolaren Menge n-Butyllithium (1,6 M Lösung in n-Hexan) dargestellt. Bereits während der Reaktion fiel das Amid aus.…”

“…The unusually acute N1-Si1-N2 angle in the title compound is associated with Si-N distances of 1.7436(17) Å (Si1-N1) and 1.7445(17) Å (Si1-N2). The latter are remarkably longer than the value reported for a Si-N single bond (1.724(4) Å [13]), but correspond to those in related cyclodisilazanes [14][15][16][17][18][19][20][21][22]. Consequently, the P-N bonds are shorter than expected for a single bond (1.6857(17) Å (P1-N1) and 1.6854(17) Å (P1-N2) vs. 1.704(4) Å [13]).…”

“…In these structures, the corresponding dihedral angles between the data reports planar Si 2 N 2 core and the aromatic rings lie in in the range 3 to 8 . However, when the ortho substituents are methyl or isopropyl groups, these angles increase to almost 90 due to steric interactions between the ring systems (Schneider et al, 2001;Shah et al, 1996). The Si-C6-C7 or SiA-C6A-C7A planes in the molecule are almost perpendicular to the central Si 2 N 2 core with dihedral angles of 89.73 (6) .…”
