A metal-organic coordination polymer formulated as [Ni(cbba)(2)(bipy)(H2O)(2)](n) 1 (H(2)cbba = 2-(4'-chlorine-benzoyl)benzoic acid, bipy = 4,4'-bipyridine) has been hydrothermally synthesized and structurally characterized by elemental analysis, IR spectrum, TG and single-crystal X-ray diffraction. The title compound crystallizes in the triclinic system, space group P (1) over bar with a = 5.4550(4), b = 11.4099(8), c = 15.3135(11) angstrom, alpha = 68.7680(10), beta = 81.3470(10), gamma = 79.3450(10)degrees, V = 869.48(11) angstrom(3), C38H28Cl2N2NiO8, M-r = 770.23, D-c = 1.471 g/cm(3), mu(MoK alpha) = 0.768 mm(-1), F(000) = 396, Z = 1, the final R = 0.0456 and wR = 0.1171 for 2477 observed reflections (I > 2 sigma(I)). It exhibits a one-dimensional chain-like structure.
