Figure 4
The hydrogen-bond network of (II) (a) along the c axis and (b) along the a axis, and (c) the hydrogen-bonded two-dimensional sheet. The black dotted lines are hydrogen bonds between solvent water molecules and uncoordinated O atoms of 3,3′-TPDC ligands, as well as hydrogen bonds between coordinated water molecules and uncoordinated O atoms of 3,3′-TPDC ligands. The green dotted lines are hydrogen bonds between coordinated amine H atoms and solvent water O atoms. All of the H atoms, except for those involved in hydrogen bonds, have been omitted for clarity. |
