Abstract

Assemblies of Cu(II) chloride with dicyanamide (dca) anion and a tripyridyltriazole co-ligand 3,4-bis(2-pyridyl)-5-(3-pyridyl)-1,2,4-triazole (L223) under different ligand-to-metal ratios produce two coordination polymers {[Cu5(L223)4(dca)10](H2O)2}n (1) and [Cu(L223)(dca)Cl]n (2), displaying distinct 1D double-chain array and 3D chiral dia network, respectively. Weak antiferromagnetic exchanges are observed in both coordination polymers.

Graphical abstractTwo distinct 1D and 3D Cu(II) coordination polymers can be assembled based on dicyanamide anion and a tripyridyltriazole tecton, through simply adjusting the ligand-to-metal ratios, in both of which weak antiferromagnetic interactions are observed between the metal ions.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► Ligand-to-metal ratio dependent assembly of two Cu(II) coordination polymers can be achieved. ► The two coordination polymers show distinct 1D double-chain array and 3D chiral dia network. ► Weak antiferromagnetic interactions between the Cu(II) ions are observed in both systems.
