THE ABSOLUTE CONFIGURATION OF S-(+)-1-p-CHLOROPHENYL-4-ETHYL-2,8,9-TRIOXA-5-AZA-1-SILATRANE(3.3.3.01.5) UNDBCANE

<正> The title compound crystallized in orthorhombic system with space group P212121 and cell dimensions a=9.805(2),b=11.381(4), c=13.865(4) A,V= 1547.0A3, Z=4,Dc=1.345 g.cm-3,λ=1.5418A,μ=13.067 cm-1.The structure was solved by direct methods and refined by block-diagonal least-squares method to the final discrepancy factors R=0.042 and Rw=0.042 for 1101 reflections with I>2.50σ(I). The absolute configuration was determined by utilizing the anomalous scattering of the Si and Cl atoms.It has the S configuration. The Si←N bond length is 2.146(5)A.
