Crystal structure of 1: (a) the dinuclear {Cd(1)2} secondary building unit and (b) the mononuclear Cd(2) building unit, showing the coordination sphere of the Cd(II) center, (c) the coordination mode of btc3− ligand, (d) the topological 8-connected node of the {Cd(1)}2 SBU, (e) the topological 6-connected node of the mononuclear Cd(2) unit, (f) the topological 4-connected node of the btc3− ligand, (g) polyhedral and (h) space-filling model representations of the three-dimensional open framework, and (i) schematic representations of the (4,6,8)-connected net topology.
