The title compound, [Cu(dpa)(2,2’-bipy)(H2O)2]n 1 (H2dpa = diphenic acid and 2,2’- bipy = 2,2’-bipyridine), has been synthesized and its structure was determined by single-crystal X-ray diffraction. The crystal is of orthorhombic, space group P212121 with a = 10.597(4), b = 11.317(4), c = 17.630(7) , V = 2114.3(14) 3, C24H20CuN2O6, Mr = 495.97, Z = 4, Dc = 1.558 g/cm3, μ = 1.079 mm-1, F(000) = 1020, Flack value = 0.052(18), R = 0.0430 and wR = 0.1016 for 3381 observed reflections (I > 2σ(I)). In compound 1, the dpa ligands link metal ions into helical structures in the same direction. The title compound, [Cu (dpa) (2,2’-bipy) (H2O) 2] n 1 (H2dpa = diphenic acid and 2,2’-bipy = 2,2’-bipyridine), has been synthesized and its Structure was determined by single-crystal X-ray diffraction. The crystal is of orthorhombic, space group P212121 with a = 10.597 (4), b = 11.317 (4), c = 17.630 (7) Ck3, C24H20CuN2O6, Mr = 495.97, Z = 4, Dc = 1.558 g / cm3, μ = 1.079 mm-1, F000 = 1020, Flack value = 0.052 (18), R = 0.0430 and wR = 0.1016 for 3381 observed reflections (I> 2σ (I)). In compound 1, the dpa ligands link metal ions into helical structures in the same direction.
