A novel manganese(Ⅱ) coordination polymer [Mn(L1)2(H2O)]·2H2O (HL1 = 2,6-dichlorobenzoic acid) 1 has been synthesized and structurally characterized.X-ray diffraction analyses reveal that 1 is a one-dimensional chain structure bridged by water molecules and 2,6-dichlorobenzoic acid.The crystal is of monoclinic,space group P21/c with a = 12.9701(19),b =20.592(3),c = 7.3759(10) (A),β = 102.660(2)°,V = 1.9221(5) nm3,Z = 4,C14H12Cl4MnO7,Mr=488.98,Dc = 1.690 g/cm3,μ = 1.275 mm-1,F(000) = 980,Rint = 0.0348,R = 0.0350,and wR =0.0755.In the crystal the manganese atom is six-coordinated by two oxygen atoms from water and four oxygen atoms from four 2,6-dichlorobenzolate molecules,completing an octahedral geometry.
