Syntheses and crystal structures of three one-dimensional copper(II) complexes constructed by salicylate and 4,4′-bipyridine: ladder, zig-zag, and linear polymeric assembly

摘要: Abstract Syntheses and crystal structures of three new compounds {trans-[Cu(Hsal)2(4,4′-bipy)](DMF)}n (1), {cis-[Cu(Hsal)2(4,4′-bipy)](2H2O)}n (2), [Cu2(Hsal)4(4,4′-bipy)]n (3) are reported. These have trans-, cis-, dimer geometries bearing a common motif [Cu(Hsal)2(4,4-bipy)n] leading to ladder, zig-zag, linear one-dimensional (1-D) networks, respectively. The Cu⋯Cu distances separated by 4,4′-bipy different in these compounds, which leads an extension structure compound 3 compact 2. Conformations ligands also different. In 1 there is stacking the bidentate salicylate bridging from another molecule. There molecule
