•The CP [Ag5(CN)5(2,2′-bpy)2]n, 1 was obtained based on AgCN and 2,2′-bipyridine.•Six-membered rings are formed of 1D-puckered AgCN chains and 2,2′-bpy in 1.•3D-network structure of 1 is created via H-bonds, π–π stacking and Ag–Ag interaction.•The CP 1 was used as heterogeneous catalyst for the degradation of MB dye.
Colorless crystals of the coordination polymer (CP) [Ag5(CN)5(2,2′-bpy)2]n, 1 were obtained by the reaction of AgNO3, 2,2′-bipyridine (2,2′-bpy) and KCN. The crystal structure of 1 consists of 1D-puckered AgCN chains which are decorated by 2,2′-bpy molecules. These chains form 2D-fused deformed six-membered rings; [Ag4(CN)2(2,2′-bpy)2] creating wide voids capable to accommodate the 2,2′-bpy molecules. 3D-network structure is created via H-bonds, π–π stacking and Ag–Ag interaction. The structure of the CP 1 was characterized by IR, UV–Vis, TGA, NMR spectra and X-ray single crystal analysis. The CP 1 was used as heterogeneous catalyst for the oxidative discoloration of methylene blue dye (MB) by H2O2.
