Crystal structure, Hirshfeld analysis and electrochemical properties of poly[diaquabis[μ<sub>6</sub>-2-cyano-2-(oxidoimino)acetato]copper(II)disodium]
The title compound, [Na<sub>2</sub>Cu(C<sub>3</sub>N<sub>2</sub>O<sub>3</sub>)<sub>2</sub>(H<sub>2</sub>O)<sub>2</sub>] <sub><i>n</i></sub> , is a three-dimensional coordination polymer composed of divalent copper-centered complex anions, linked by sodium and water mol-ecules. The copper(II) ion adopts a distorted octahedral coordination geometry, defined by two nitro-gen atoms from oxime groups and two oxygen atoms from carboxyl-ate groups, originating from two <i>trans</i>-oriented, doubly deprotonated residues of 2-cyano-2-(hy-droxy-imino)-acetic acid. The axial Cu-O bonds are much longer than the equatorial Cu-O and Cu-N bonds due to the Jahn-Teller effect. Each complex anionic unit is linked to four neighboring anions <i>via</i> Cu-O bonds, forming a two-dimensional anionic network parallel to the <i>bc</i> plane.
