Part of the crystal structure. O—HW⋯ONA, N—HNA⋯OC and N—HNA⋯ONA (W = water, C = carboxylate and NA = nicotinamide) hydrogen bonds, enclosing R22(12), R33(8), R33(14), R33(16), R33(20), R33(22), R44(22), R55(16), R66(16) and R66(18) ring motifs are shown as dashed lines. C-bound H atoms have been omitted for clarity. |
