A unique coordination polymer, {[CuLNa(ClO 4 )]·H 2 O} n (1), was isolated from the solution containing sodium perchlorate and the neutral macrocyclic oxamidocopper(II) complex [CuL] (H 2 L = 2,3‐dioxo‐5,6:13, 14‐dibenzo‐7, 12‐bis(ethoxycarbonyl)‐1, 4, 8, 11‐tetraazacyclotetradeca‐7, 11‐diene). The complex is composed of [Na 2 Cu 2 ] tetrametallacycles bridged by perchlorate ions to form infinite one‐dimensional chains which are stacked via τ‐τ interactions and weak coordination bonds to result in a two‐dimensional supramolecular network. The perclorate ions were found to coordinate to sodium atoms in the unusual bridging chelating tridentate mode of μ 2 ‐(O:O′,O″).
