摘要：
The title complex [Cu(4,4'-bpy)(H2O)(3)]SO4.2H(2)O (M-r = 405.86) was synthesized under hydrothermal conditions and its crystal structure has been determined by X-ray diffraction. It crystallizes in the hexagonal system, space group P6(1) with a = 11.1870(4), c = 21.578(l) Angstrom, V = 2338.6(2) Angstrom(3), D-c = 1.729 g/cm(3), Z = 6, mu(MoKalpha) = 1.583 mm(-1) and F(000) = 1254. The final R and wR are 0.0253 and 0.0416 for 1458 observed reflections with Igreater than or equal to2sigma(I), respectively. It was revealed that the square pyramidal Cu(II) sites are linked through 4,4'-bipyridine groups, forming infinite one-dimensional chains, with the sulfate anions and lattice water molecules occupying the inter-chain positions. During the electrostatic interactions, there exist O...O hydrogen bonds and pi-pi stacking interactions between the parallel aromatic bipy rings in the structure.
