A new coordination polymer [Mn2(NDC)2(DMF) 2(H2O)]n · nDMF (1) has been synthesized by the reaction of MnCl2·4H2O with 2, 6-naphthalenedicarboxylic acids (H2NDC) under ambient conditions in DMF. A single crystal X-ray diffraction measurement reveals that 1 crystallized in the orthorhombic space group Pbca with a = 1.8334(2) nm, b = 1.6046(17) nm, c = 2.3706(3) nm, V = 6.974(13) nm3, Z = 8, Dc = 1.471 g/cm3, Mr = 772.50, μ = 0.790 mm-1, F(000) = 3176, S = 0.951, (Δ/σ)max = 0.001, Δρ min = 0.539, Δρmin = -0.351, R = 0.0335, wR = 0.0859. The combination of octahedral manganese (II) ions and NDC ligands leads to the formation of infinite three-dimensional (3D) networks, which have lozenge-shaped 1D channels (0.7 nm × 1.2 nm) along the crystallographic b-axis. The cavities are filled with coordinated solvent molecules (DMF) and non-coordinated ones.
