摘　　要：A 3D homochiral coordination polymer [Mn（edca）]n（1） was synthesized from a flexible coupled cinnamic acid ligand, 2,2？-（ethane-1,2-diylbis（oxy）） dicinnamic acid（H_2 edca） and MnCl_2×4 H_2 O under solvothermal conditions. The complex crystallizes in orthorhombic, space group P2_12_12_1 with a = 5.5785（8）, b = 13.0393（18）, c = 23.133（3） A, V = 1682.7（4） A^3, M_r = 407.27, D_c = 1.608 Mg/cm^3, F（000） = 836, Z = 4, the final R = 0.0240 and wR = 0.0590 for 2983 observed reflections（I 〉 2σ（I））. In 1, the edca2＋ anions alternately bridge the Mn（Ⅱ） cations to form one-dimensional（1 D） infinite helical chains of [Mn（edca）]n, which are further connected by the ligands generating a three-dimensional（3D） homochiral network. The photoluminescence of 1 was also investigated in solid state at ambient temperature.A 3D homochiral coordination polymer [Mn（edca）]n（1） was synthesized from a flexible coupled cinnamic acid ligand, 2,2？-（ethane-1,2-diylbis（oxy）） dicinnamic acid（H_2 edca） and MnCl_2×4 H_2 O under solvothermal conditions.
