For the first time, the X-ray structure of nicotinamide riboside could be determined. Five nicotinamide riboside (NR) derivatives in their native, thioamide and triacetyl protected form could be crystallized as their chloride and bromide salts. The single crystals were obtained with the help of the vapor diffusion technique. The use of the much slower layering technique for crystallization led to the decomposition of the nicotinamide ribosides yielding the corresponding nicotinamide salts. The χ torsion angles of the five nicotinamide riboside derivatives were compared with those obtained from the two nicotinamide adenine dinucleotide crystal and the three protein nicotinamide riboside cocrystal structures.
