A novel manganese(II) coordination polymer [Mn(pdc)]n (pdc = pyridine-2,4- dicarboxylate) has been synthesized under hydrothermal conditions. The crystal is of monoclinic, space group P21/n with a = 6.506(4), b = 9.392(6), c = 11.217(7) , β = 105.650(12)o, V = 660.0(7) 3, Z = 4, Mr = 220.04, Dc = 2.215 g/cm3, μ = 1.971 mm-1, F(000) = 436, Rint = 0.0345, R = 0.0360 and wR = 0.0778 for 1259 observed reflections with I > 2σ(I). In the structure, the Mn(Ⅱ) atom is coordinated in a distorted octahedral arrangement by one pyridine N and five carboxylate O atoms from five pdc ligands, each of which coordinates to five Mn atoms to propagate a three-dimensional layered framework.
