Abstract

Reaction of Bi(OtBu)3 with aspirin (acetylsalicylic acid = aspH) in dry toluene results in the bismuth(iii) complex, [Bi(O2C(C6H4)OAc)3]∞ 1 (O2C(C6H4)OAc = asp), minimum inhibitory concentration (MIC) against Helicobacter pylori ≥ 6.25 μg mL-1, while the inclusion of a stoichiometric equivalent of KOtBu leads to crystals of the bismuthate salt [KBi(O2C(C6H4)OAc)4]∞ 2.
