Figure 3
A partial packing diagram for (I) , viewed approximately along the a axis, showing the hydrogen-bonded chain structure. Dashed lines show N—H⋯O and O—H⋯O hydrogen bonds. H atoms not involved in the hydrogen bonds have been omitted. [Symmetry codes: (ii) -x+2, -y+1, -z+1; (iii) -x+1, -y+1, -z; (vi) x+1, y, z+1.] |
