Crystal structure of 5-(dibenzo-furan-4-yl)-2'-deoxy-uridine.

The mol-ecule of the title compound, C21 H18 N2 O6 , has a bent rather than a linear conformation supported by three intra-molecular C-H⋯O hydrogen bonds. The packing in the crystal lattice is largely determined by inter-actions between hydrogen atoms with oxygen atom lone pairs with one mol-ecule inter-acting with neigbouring mol-ecules via O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds. The title compound crystallizes in the chiral ortho-rhom-bic space group P 21 21 21 . Its absolute structure could not be determined crystallographically and was assumed with reference to that of the reactant 5-iodo-2'-de-oxy-uridine.
