Abstract
The structure of the title compound, C27H47N5O4Si3, has been determined at 223 K. There are two independent molecules per asymmetric unit. The main st ructural characteristics are as follows: (i) the compound has a 2'S configu ration and (ii) the furanose part of the molecule adopts a 3'-endo conforma tion [pseudorotation phase angles 27.5 (2) and 26.8 (3)degrees].
