Crystal structure of 5-(dibenzofuran-4-yl)-2′-deoxyuridine

Abstract

The molecule of the title compound, C21H18N2O6, has a bent rather than a linear conformation supported by three intramolecular C—H...O hydrogen bonds. The packing in the crystal lattice is largely determined by interactions between hydrogen atoms with oxygen atom lone pairs with one molecule interacting with neigbouring moleculesviaO—H...O, N—H...O and C—H...O hydrogen bonds. The title compound crystallizes in the chiral orthorhombic space groupP212121. Its absolute structure could not be determined crystallographically and was assumed with reference to that of the reactant 5-iodo-2′-deoxyuridine.
