A novel Co (II) ‐ Na (I) heterometallic coordination polymer {[CoNa (NTA) (H 2 O) 3 ] · 2H 2 O} 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.
