One-dimensional cobalt and zinc complexes involving in situ reaction of ethylenediamine and acetonitrile to form imidazoline ligand

The solvothermal treatment of cobalt nitrate (or zinc acetate), ethylenediamine and dicarboxylate in acetonitrile produced two one-dimensional coordination polymers [Co(mimz)2(ox)]n (1) and [Zn(mimz)2(ip)]n (2) (mimz = 2-methylimidazoline, ox = oxalate, ip = isophthalate) which ligand involving in situ formation of imidazoline ligand by cycloaddition reaction of ethylenediamine and acetonitrile.
