摘要：

The synthesis and X-ray characterization of two supramolecular isomers, [Co(oba)(2,20-bpy)](n) (1 and 2) (oba 4,4'-oxybis(benzoate), 2,2'-bpy 2,2'-bipyridine) are reported. Crystal data for 1: a 12.026(2), b = 15.120(3), c = 11.361(2) angstrom, beta = 91.46(3)degrees, Z = 4, R-1 = 0.0330, wR(2) = 0.0949. Crystal data for 2: a = 16.171(3), b = 19.162(4), c = 22.914(5) angstrom, alpha = 107.66(3), beta = 91.46(3), gamma = 98.99(3)degrees, Z = 2, R-1 = 0.0388, wR(2) = 0.0456. They are conformational supramolecular isomers without solvent molecules in the structures, and exhibit different one-dimensional helical structures that are further assembled into distinct two-dimensional layers via pi-pi stacking interactions. The results indicate that the geometry of ligand is one of the most important factors for the construction of a helical motif.
