A new metal-organic coordination polymer [Ni[(2-pya)2(4,4-bipy)]n.6nH2O (2-pya = 2-pyridinecarboxylic acid, 4,4-bipy = 4,4-pyridine) 1 has been hydrothermally synthesized and structurally characterized by elemental analysis, IR spectrum, TG and single-crystal X-ray diffraction. The complex crystallizes in tetragonal, space group I41/a with a = b = 22.5642(19), c =10.7118(18) (A°), V = 5453.8(11) (A°)3, C22H28N4NiO10, Mr= 567.19, Dc=1.382 g/cm3, μ(MoKα) =0.769 mm-1, F(000)= 2368, Z = 8, the final R = 0.0572 and wR = 0.1254 for 1401 observed reflections (I> 2σ(I)). It exhibits a one-dimensional chain-like structure by mixed ligands of 2-pyridinedicarboxylic acid and 4,4-pyridine.
