The hydrothermal synthesis of a new metal-organic framework (MOF) formulated as Cu{sub 2}(4,4'-bpy){sub 2}SO{sub 4}.6(H{sub 2}O), [abbreviation: (1); bpy or 4,4'-bpy=4,4'-bipyridine; SO{sub 4}{sup 2-}=sulfate group] has been reported. The structure of this MOF consists of Cu{sup +} nodes connected via 4,4'-bpy to form infinite chains, with two neighboring chains further bridged on the nodes by SO{sub 4}{sup 2-}, resulting in a 1-D double chain network. Guest water molecules reside in between the chains and are hydrogen-bonded to the O and S atoms from the nearest sulfate groups, leading to the formation of a 3-D supramolecular framework. This MOF is good heterogeneous catalyst for the cyclopropanation of styrene, with high trans cyclopropane diastereoselectivity and was recycled and reused for three consecutive cycles without a significant loss of catalytic activity. - Graphical Abstract: A new MOF structure built up of 4,4{sup '}-bipyridine, sulphate and Cu(I), is an active heterogeneous catalyst for cyclopropanation of styrene with ethyldiazoacetate. Highlights: > The synthesis is different from solvothermal synthesis for other Cu(I) compounds. > The compound and the structure are new. > H bonds form infinite planes among water molecules and sulphate species. > H bonding interaction makes the structure into a 3D supramolecular framework. > Active catalytic property as heterogeneous catalyst for cyclopropanation of styrene.
