Figure 3
Part of the crystal structure of salt (I), showing the formation of a hydrogen-bonded C(7) chain parallel to [001] and built from nicotinate anions only. Hydrogen bonds are shown as dashed lines and, for the sake of clarity, H atoms not involved in the motif shown have been omitted. Atoms marked with an asterisk or a hash symbol (#) are at the symmetry positions (x, −y + 2, z − ) and (x, −y + 2, z + ), respectively. |
