Silver based Metal Organic Framework (MOF) materials were synthesized by the reaction of phospho-benzoic acid with silver salts under hydrothermal treatment and with/without urea. According to this procedure, either both functional groups (phosphonic acid and carboxylic acid) were engaged in iono-covalent bonds with silver atoms or, on the contrary, only the phosphonic acid function is engaged. Consequently, these materials exhibited different stability and their ability to release silver salts, when they were placed in water, was different. The antibacterial properties of these materials were attributed to the silver salt, released in solution.
