Figure 2.

(a) Ball-and-stick diagrams of 1 viewed along the crystallographic c-axis (left) and b-axis (right), respectively, where [Cu₃Cl₂] SBU as 8-c nodes are represented by pink spheres and the linkers between the 8-c nodes are represented by the green sticks. (b) A [Cu₃Cl₂(tz)₈] cluster (top) and the [Cu₃Cl₂] SBU as an 8-c node (bottom). (c) The space-filling diagrams of 1 drawn as the same view as the ball-and-stick diagrams in (a). (d) A 1-D channel viewed along the crystallographic b-axis, where a CO₂ is ligated to Cu(II) site. Ball-and-stick diagrams of the single crystal structures of (e) MeOH-bound 1a at 173 K, (f) CO₂-bound 1a at 195 K, and (g) CO₂-bound 1a at 296 K.
