Abstract A new two‐dimensional (2D) polymer, [Cu(pmt)(dca)] n [pmt = 2‐(2‐pyridymethylamino)ethanesulfonate, dca = dicyanamide] ( 1 ), was synthesized and characterized by single‐crystal X‐ray diffraction, elemental analysis, IR spectroscopy, and magnetic measurements. X‐ray structure analysis revealed that the compound contains [Cu(μ 1,5 ‐dca)] n chains, which are further connected by bridging sulfonate anions of pmt ligands to result in (4,4)‐connected 2D sheets. The magnetic susceptibilities (2–300 K) of 1 were investigated, and indicated that the complex exhibits a weak ferromagnetic interaction between the copper(II) ions.
