Figure 4
The molecular conformation and atom-numbering scheme for the INIPA cation, the TPA dianion and the solvent water molecule in the asymmetric unit of (IV). The dianion has inversion symmetry [symmetry code: (i) −x, −y + 1, −z]. Displacement ellipsoids are drawn at the 40% probability level and inter-species hydrogen bonds are shown as dashed lines. |
