By hydrothermal synthesis, a manganese(II) tetracarboxylate [Mn(2,2′-bipyridi- ne)(btec)0.5(H2O)]2n (H4btec = 1,2,4,5-benzenetetracarboxylic acid) was obtained and characteri- zed by single-crystal X-ray diffraction, IR, elemental analysis and thermogravimetric analysis. It crystallizes in triclinic, space group P1, with a = 7.721(4), b = 8.905(5), c = 10.712(6), α = 80.899(8), β = 70.371(8), γ = 78.201(8)°, Z = 2, V = 675.8(7) 3, Mr = 354.20, Dc = 1.741 g/cm3, μ = 1.007 mm-1, F(000) = 360, S = 0.956, (△/σ)max = 0.000, the final R = 0.0490 and wR = 0.1262. This compound presents an infinite 1D polymer featuring a double-chain structure. The Mn(II) ion is five-coordinated. The four carboxylate groups of btec4- are all deprotonated and coordinated to four Mn atoms in a monodentate fashion, forming a 1D double chain structure with a cavity. Such chains are interconnected by π-π stacking interactions into 2D layers which are further interlinked into a supramolecular structure by hydrogen bonds.
