Ultrasound-assisted synthesis and biological activity of nanosized supramolecular coordination polymers of silver(I) with chloride, thiocyanate, and 4,4′-bipyridine ligands

•[AgCl(bpy)2] and [(AgSCN)2(bpy)0.5] had been synthesized by ultrasonic waves.•The structures were investigated by X-ray diffraction of single crystals.•TEM images support nanosized particles of SCPs1 and 2.•Biological and and antimicrobial activities had been investigated.
