Hydrolysis of either Bi(HSal4Me)3 or [Bi22O26(HSal4Me)14] in dmso gave the 4-methylsalicylate-substituted bismuth oxido cluster [Bi38O45(HSal4Me)24(dmso)14(H2O)2]·4H2O. 1H DOSY NMR and ESI-FTICR MS revealed an on-going growth process to finally give the large cluster. Microbiological activity tests against three strains of H. pylori showed higher activity for smaller bismuth species.
