The action of Pepto-Bismol arising from the structure and hydrolysis of bismuth subsalicylate (BSS) is not yet understood. Two bismuth oxosalicylate clusters, [Bi38O44(HSal)26(Me 2CO)16(H2O)2] (1) and [Bi 9O7(HSal)13(Me2CO)5] (2), have been characterized which provide structural insight into the nature of BSS. A Bi9O7 cluster forms the core of 2 and is found at the heart of 1 (see picture; core Bi atoms: green, core O atoms: red). (Figure Presented).
