Abstract: In the structure of the title compound, [CuNa₂(C₂H₃O₂)₂(N₃)₂]_n, the copper(II) cation is coordinated by two N atoms of two symmetry-related azide anions and two O atoms of two symmetry-related carboxylate anions within a distorted tetragonal plane. The sodium cation is surrounded by four O atoms of four symmetry-equivalent carboxylate anions and two N atoms of two azide anions within an irregular polyhedron. The copper(II) cations are located on a twofold axis, whereas all other atoms are located in general positions. The copper(II) and sodium cations are connected via the carboxylate anions into sheets parallel to (010). These sheets are linked by the azide anions via -N,N coordination into a three-dimensional coordination network.
