STRUCTURE OF 1-CHLOROMETHYL-2,8,9-TRIOXA-5-AZA-3,4-BENZO-7,10- DIMETHYL-l-SILATRICYCLO-(3,3.3.O~(1,5))-UNDECANE

<正> Mr=299.8, triclinic, Pl, a=10.395(2), b=11.191(2), c=14.051(3)A, α=81.80(2), β=89.42(2), r=66.47(1)°, v=1481.4(5)A3, Z=4, μ(MoKα)=3.37 cm-1, F(000)=632, Dx=1.34 g/cm3, room temperature. The final R=0.058, with unit weights and s=1.33 for 2900 independent reflexions with |Fo| ≥2.5σ(|Fo|). There are two molecules in an asymmetric unit and the lengths of dative N→ Si bond for the two molecules are 2.185(4) and 2.177(4)A, respectively. The different conformations were observed due to the rotation of the chloro-methyl groups.
