Abstract
Preparation and spectroscopic data of the new compounds Si3O3(NHCH3)6 (1), Si3O2(NCH3)(NHCH3)6 (2 ), (CH3)3Si-NCH3-Si2OCl5 (3 ), ((CH3)3Si-NCH3)2Si2OCl4 (4) and [Cl3Si-O-SiCl2-NCH3-AlCl2]2 (5) are reported. The structure of the chlorinated alummosiloxazane compound has been determined by single crystal X-ray analysis (space group P1̄, a = 8,357(1), b = 9,538(1), c = 9,774(1) Å, α = 85,35(1), β = 65,39(1), γ = 71,97(1)°, 2620 data (F0 > 3σ(F0), R = 0,040). The molecule shows a dimetric structure and contains a planar four-membered Al2N2 ring with Si2OCl5 groups in trans-position.
