5-Amino-1-(2′,3′-O-isopropylidene-d-ribityl)-1H-imidazole-4-carboxamide: a crystal structure with Z′ = 4

The title compound, C12H20N4O5, crystallizes in the monoclinic space group P21, with four crystallographically independent molecules in the asymmetric unit. The four molecules have a very similar conformation that is basically determined by the formation of two intramolecular hydrogen bonds between...
