Abstract:
The title compound [systematic name: 1-(2-deoxy-β-D- erythro -pentofuranosyl)-4-nitro-1 H -pyrrolo[2,3- b ]pyridine] , C 12 H 13 N 3 O 5 , forms an intramolecular hydrogen bond between the pyridine N atom as acceptor and the 5′-hydroxy group of the sugar residue as donor. Consequently, the N-glycosylic bond exhibits a syn conformation, with a χ torsion angle of 61.6 (2)°, and the pentofuranosyl residue adopts a C2′- endo envelope conformation ( 2 E , S -type), with P = 162.1 (1)° and τ m = 36.2 (1)°. The orientation of the exocyclic C4′—C5′ bond is + sc ( gauche , gauche ), with a torsion angle γ = 49.1 (2)°. The title nucleoside forms an ordered and stacked three-dimensional network. The pyrrole ring of one layer faces the pyridine ring of an adjacent layer. Additionally, intermolecular O—H...O and C—H...O hydrogen bonds stabilize the crystal structure.
