With <b>L</b>, one metallomacrocycle and three metal-organic frameworks, [Cu(L)(OAc)<sub>2</sub>(H<sub>2</sub>O)·2H<sub>2</sub>O]<sub><i>n</i></sub> (<b>1</b>), [Co(L)<sub>2</sub>(NO<sub>3</sub>)<sub>2</sub>(H<sub>2</sub>O)<sub>2</sub>·4H<sub>2</sub>O]<sub><i>n</i></sub> (<b>2</b>), [Zn(L)<sub>2</sub>(NO<sub>3</sub>)<sub>2</sub>(H<sub>2</sub>O)<sub>2</sub>·7H<sub>2</sub>O]<sub><i>n</i></sub> (<b>3</b>), and [Cu(L)(I)·DMF]<sub><i>n</i></sub> (<b>4</b>) were crystallized, which display three different structure types. In <b>1</b>, two ligands are arranged in a face-to-face conformation to coordinate two Cu(II) ions from opposite directions through axial positions, generating a pesudo-rectangular metallomacrocycle. Polymer <b>2</b> is an 1D double ribbons. Interestingly, each double ribbons is connected by hydrogen bond with the result that the channels are formed and run parallel to the <i>ab</i> diagonal, and the water chains with the symbol C4 are located within the channels. Polymer <b>3</b> exhibits the same topological morphology as polymer <b>2</b>. However, each double ribbons in <b>3</b> is connected by a different type of hydrogen bond with the result that the channels are formed along the <i>b</i> axis. Polymer <b>4</b> is a two-dimensional (2D) tubular sheet constructed by an unprecedented [CuI]<sub>∞</sub> column and clip ligand <b>L</b>. The type of the [CuI]<sub>∞</sub> column can be described as a zigzag chain and has been rarely reported. The DMF solvent molecules are located within the channels. clip ligand L;symbol C 4;DMF;ribbon;metallomacrocycle;type;CuI;H 2 O;Cu;Polymer 3 exhibits;hydrogen bond 2008-05-07
