Assembly and structures of five new Cu(II) complexes based on the V-shaped building block [Cu(dbsf)]

摘要: Abstract Five new copper(II) complexes [Cu(dbsf)(H2O)]n · 0.5n(i-C3H7OH) (1), [Cu(dbsf)(4,4′-bpy)0.5]n · nH2O (2), [Cu(dbsf)(2,2′-bpy)(H2O)]2 · (n-C3H7OH) · 0.5H2O (3), [Cu(dbsf)(phen)(H2O)]2 · 1.5H2O (4) and [Cu(dbsf)(2,2′-bpy)(H2O)]n · n(i-C3H7OH) (5) (H2dbsf = 4,4′-dicarboxybiphenyl sulfone, 4,4′-bpy = 4,4′-bipyridine, 2,2′-bpy = 2,2′-bipyridine, phen = 1,10-phenanthroline, i-C3H7OH = isopropanol, n-C3H7OH = n-propanol) have been synthesized under hydro/solvothermal conditions. All of the are assembled from V-shaped building blocks, [Cu(dbsf)]. Complex 1 is composed 1D double-chains. In complex 2, dbsf2− ligands 4,4′-bpy connect Cu(II) ions into catenane-like 2D layers. These layers stack in an ABAB fashion to form a 3D supramolecular network. Complexes 3 4 0D dimers, which two [Cu(dbsf)] units encircle dimetal macrocyclic molecules. However, 5, blocks joined head-to-tail, resulting formation infinite tooth-like chains. The different structures 5 may be attributed solvent molecules included.
