Abstract

Two propylene‐bridged bis‐benzotriazole ligands, 1 and 2, were used to obtain three novel coordination polymers with cobalt(II), copper(II) and copper(I). The complexes were structurally characterised by X‐ray crystallography. The complex [Co(1)Cl~2~]~n~, 3, possesses a helical zigzag chain structure in which tetrahedral CoCl~2~ centres are bridged by molecules of 1 having an extended conformation. The complex [Cu(1)Cl~2~]~n~, 4, exhibits a more complex supramolecular architecture, which extends in two dimensions, with bridging through Cu~2~Cl~4~ dimeric units in one direction and through the organic ligand in an orthogonal direction. The complex [Cu(2)Cl]~n~, 6, has a one‐dimensional polymeric structure involving 16‐membered M~2~L~2~ rings bridged by Cu~2~Cl~2~ units. (© Wiley‐VCH Verlag GmbH & Co.
