The title complex has been obtained by the reaction of cobalt sulfate heptahydrate with 4,4?-bpy and 4-abaH (4,4?-bpy = 4,4?-bipyridine, 4-abaH = 4-aminobenzonic acid) in ethanol solution, and its structure was determined by X-ray crystallography with the following data: tetragonal, space group P42/n, Mr = 5692.46, Co8C192H288N32O120S8, a = b = 16.402(5), c = 22.750(5) ?, Z = 1, V = 6120(2) ?3, F(000) = 2968, Dc = 1.544 g/cm3, μ = 0.707 mm-1, the final R = 0.0786 and wR = 0.1935 for 2673 observed reflections (I > 2σ(I)). The title complex consists of polymeric [Co(4,4?-bipy)(H2O)4]2+ cation chains, SO4 2- anions, lattice 4-abaH and water mole- cules. The center CoII ions are connected by bridging 4,4?-bpy ligands exhibiting one-dimensional chains, and coordinated by four water molecules into a distorted octahedral geometry. These chains are further extended by hydrogen bonds among SO4 2- anions, coordinated and lattice water molecules as well as lattice 4-abaH molecules into a three-dimensional network.② Corresponding author. male, 48, associate professor, research interest in coordination chemistry.rrrrrrrrn E-mail: thjchen@jnu.edu.cnrrrrrrrrn② Corresponding author. male, 48, associate professor, research interest in coordination chemistry.rrrrrrrrn E-mail: thjchen@jnu.edu.cn
