A novel Co(II)-Na(I) heterometallic coordination polymer {[CoNa(NTA)(H 2O) 3]·2H 2O} n (NTA=nitrilotriacetate) was synthesized and characterized by elemental analysis and X-ray diffraction study. The electrochemical behavior in aqueous solution was measured by cyclic voltammetry, indicating a quasi-reversible process. The complex crystallizes in the orthorhombic space group Pbca with the cell parameters a=1.47276(3) nm, b=0.97280(3) nm, c=1.92946(6) nm, V=2.76434(13) nm 3, Z=8. In the title complex, there are two kinds of zigzag chains which interconnect together to form 2D network. One stretches along the b-axis, comprising Co(II) ions, the other stretches along the c-axis, comprising Na(I) ions.
