Title: Hydrothermal Synthesis and Structure of a Copper(II) Complex, [Cu(4,4′-bpy)(H2O)3]SO4·2H2O
Abstract: The title complex [Cu(4,4′-bpy)(H2O)3]SO4·2H2O (Mr=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 P61 with α=11.1870(4), c=21.578(1)A, V=2338.6(2)A3, Dc=1.729g/cm3, Z=6,μ(MoKα)=1.583mm-2 and F(000)=1254. The final R and wR are 0.0253 and 0.0416 for 1458 observed reflections with 1≥2σ(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 π-π stacking interactions between the parallel aromatic bipy rings in the structure.
