摘要：
A novel chiral 2-D layer coordination polymer [Co(Pydc)(H2O)2] · H2O (Pydc = Pyridine-2,5-dicarboxylate) was hydrothermally synthesized and characterized by elemental analysis, IR spectra and TG analysis. Single-crystal X-ray diffraction shows that Co(1) was connected by the oxygen atom and nitrogen atom of different carboxyls and form a helical-shaped {O(3)-Co-N}n chain along 21 helical axes. The adjacent 1-D {O(3)-Co-N}n helical-shaped chains are developing along 21 helical axes with the same direction and are connected by O(4) to form an ordered 2-D layer. All the molecules exist in the same optical activity that imparts the chiral nature to the whole compound.
