A. Mullerfahrnow et al., MOLECULAR AND CRYSTAL-STRUCTURE OF THE BOLA-AMPHIPHILE N-[8-(D-GLUCONAMIDO)OCTYL]-D-GLUCONAMIDE, Carbohydrate research, 242, 1993, pp. 11-20
The crystal structure of the title compound [5; space group P2(1); a=8
.375(5), b=51.52(2), c=5.647(3) angstrom; beta=89.64(4)-degrees] was d
etermined by X-ray diffraction methods and refined to R=0.107. There a
re two molecules in the asymmetric unit, which adopt nearly identical
conformations. Each molecule has two parts that differ only in the tor
sion angle N-C-7-C-8-C-9, which can be synclinal (-64-degrees) or anti
(168-degrees). The molecules are arranged in sheets and the packing i
s stabilised by strong intra- and inter-molecular hydrogen bonds, some
of which form a homodromic arrangement.
