Figure 2
(a) Schematic representation of a supramolecular ladder motif in (I) formed by hydrogen-bonded rings involving metal ions, coordinated chloride ions, coordinated water molecules and uncoordinated water molecules. (b) The ladder motif as observed in the crystal lattice. Purple dashed lines indicate hydrogen bonds. The 2-TPC and OMP ligands, and H atoms not involved in hydrogen bonding, have been omitted for clarity. The symmetry codes are as given in Table 2, plus (v) x + 1, y, z; (vi) −x, −y + 1, −z + 1. |
