Figure 2
(a) The two-dimensional network and a schematic illustration of the 63 topology of (I) (the green sticks and turquoise polyhedra represent the L2− ligands and the CdII cations, respectively). (b) The three-dimensional supramolecular architecture of (I) linked by hydrogen-bonding interactions, with the one-dimensional water chains shown in space-filling mode. (c) Hydrogen bonds among the isolated water molecules, coordinated water molecules and carboxylate O atoms. [Symmetry codes: (iii) x, y − 1, z; (iv) −x + 1, −y + 1, −z + 1; (vii) −x + 1, −y + 1, −z + 2; (ix) x − 1, y, z; (x) x + 1, y, z; (xi) x + 1, y − 1, z.] |
