Abstract

Two coordination polymers, [Co(phen)(oba)(H2O)2] (1) and [Cd3(phen)3(oba)2(Hoba)2(H 2O)2] (2) (oba = 4,4′-oxybis-(benzoate), phen = 1,10-phenanthroline) have been synthesized under hydrothermal conditions. Complex 1 crystallizes in monoclinic, P21/n, a = 7.543(6), b = 33.05(2), c = 9.902(5) Å, β = 103.69(2)°, V = 2398(3) Å3, Z = 4; 2 in monoclinic, P2/n, a = 15.11(1), b = 10.069(8), c = 28.02(2) Å, β = 101.83(1)°, V = 4174(5) Å3, Z = 2. X-ray single-crystal diffraction investigations shows that the complexes 1 and 2 consist of helical chains, which are further assembled into layers and networks via supramolecular interactions such as π-π stacking interactions and hydrogen bonds, respectively. The results indicate that the coordination environment is one of the most important factors for assembly of single-stranded helical chains into double-stranded helical chains via supramolecular interactions.
