In this paper, a novel coordination polymer [Zn (pydc) (DMA)] _ n · 2 (DMA) with three-dimensional open framework structure with chiral pores was synthesized by solvothermal method. Single crystal X-ray diffraction analysis showed that the compound crystallizes in the orthorhombic space group P2_12_12_1, the unit cell parameters are a = 1.0771 (5) nm, b = 1.1528 (5) nm and c = 1.4879 = γ = 90.00 (0) °, V = 1.8475 (13) nm ~ 3. The compound is a three-dimensional network constructed by bridged Zn ions with pyridine-3,5-dicarboxylic acid (pydc) ligands.
