Figure 2 Supramolecular connectivity in (I) where hydrogen atoms are omitted for clarity. (a) The coordination environment around the W and Cu atoms. The broken lines indicate coordination to symmetry-related metal ions. (b) View along the a axis, the direction of the formed pores. (c) View along the b axis. Colour code: Light blue, orange, gray, blue, and red represent W, Cu, C, N, and O atoms, respectively. |
