Figure 4
The crystal packing of (I), showing edge-on the alternating zones of the coordination networks and the hydrogen-bonded layers. The Cu atoms are denoted by small spheres; the uncoordinated water molecules are indicated as thick isolated dots. Pale wireframe and dark wireframe denote the bipyridine and BFDC− fragments, respectively. Note that the latter are located above and below the void spaces of the Cu–bipyridine coordination networks. |
