Abstract. In an attempt to obtain new square grid polymers we could prepare the copper(II) complex [Cu(4,4’-bipy)2(H2O)2]-(sac)2 · DMF (4,4’-bipy = 4,4’-bipyridine; sac = anion of saccharin; DMF = dimethylformamide). Its structure was determined by single crystal X-ray diffraction methods. It crystallizes in the orthorhombic space group Pcnb (a = 14.4994(2), b = 15.8128(3), c = 16.6850(2) A ° , Z = 4) and is a square grid polymer with the saccharinate anions sandwiched between the complex layers and the DMF molecules filling the square holes. UV-vis, diffuse reflectance and IR spectra, room temperature magnetic susceptibility and the thermal behaviour were also investigated.
