Abstract:
A coordination polymer formulated as [Co(eoba)(phen)(H2O)2]•H2O (H2boba = 4,4΄-(ethane- 1,2-diyldioxy) dibenzoic acid, phen = 1,10-phenanthroline) has been hydrothermally synthesized and structurally characterized by elemental analysis, IR, TG and single-crystal X-ray diffraction. The title compound (C28H26CoN2O9) crystallizes in the monoclinic system, space group P2(1)/c with a = 13.708(5) Å, b = 20.237(5) Å, c = 10.158(5) Å, β = 105.071(5)˚, V = 2721.0(18) Å3, Mr = 593.44, Dc= 1.449 g/cm3, μ(MoKα) = 0.688 mm-1, F(000) = 1228, Z = 4, the final R = 0.0409 and wR = 0.0933. It exhibits a two-dimensional network structure and extended into a supramolecular framework through hydrogen bonds and π-π interactions.
