Figure 1 The structure of (I), showing the atom-numbering scheme and displacement ellipsoids drawn at the 50% probability level. Unlabelled atoms are related to the labelled atoms by the symmetry operator (−x, −y, 2-z). Intramolecular hydrogen bonds are shown as blue dashed lines and the π-stacking interaction between the central 5-aminoisophthalato ligands is indicated as a dashed green line, connecting the centroid of the atoms C1 through C6 and O1 and O2 with that of their counterparts created by the inversion center. |
