摘要：

Different types of structural connectivities, topologies, and geometrical variations are possible for a given formula unit in coordination polymers (CPs) and metal organic frameworks (MOFs) structures. This is termed supramolecular isomerism, similar to the isomerism observed in coordination complexes and organic molecules. The supramolecular isomers may exhibit different physical properties and chemical reactivities. Herein a bent dicarboxylate (sdb), a long dipyridyl spacer ligand (bpeb), and Co(II) have been used to construct two-dimensional (2D) sheets made of wheels and axles. Depending upon the experimental conditions used, seven CPs (1-7) which have the same repeating unit [Co-2(bpeb)(sdb)(2)] based on a paddlewheel structure have been isolated: a non-interpenetrated 2D sheet (1), two distortional supramolecular isomers (2 and 3), one mutually inclined interpenetrated three-dimensional structure (4), two other compounds isotypical to 2 but with two different guest solvents (5 and 6), and finally 7, a polymorph of 2. It is rather intriguing that such a simple composition can exhibit such diverse solid state structures. The magnetic properties of 2 and 3 have been discussed.
