Two novel nanoscaled bismuth oxido clusters, [Bi38O45(OMc)22(C8H7SO3)2(DMSO)6(H2O)1.5]·2.5H2O and [Bi38O45(HSal)22(OMc)2(DMSO)15(H2O)]·DMSO·2H2O

The synthesis of [Bi38O45(OMc)22(C8H7SO3)2(DMSO)6(H2O)1.5]·2.5H2O (1·2.5H2O) (OMc—methacrylate) and [Bi38O45(HSal)22(OMc)2(DMSO)15(H2O)]·DMSO·2H2O(2·DMSO·2H2O) (Hsal—salicylate) starting from [Bi38O45(OMc)24(DMSO)9]·2DMSO·7H2O and sodium 4-vinylbenzenesulfonate and salicylic acid, respectively, is presented. The bismuth oxido clusters show diameters of 2.9 nm (1) and 2.4 nm (2) and molecular weights of 11,440.22 g/mol (1·2.5H2O) and 13,151.92 g/mol (2·DMSO·2H2O). The polynuclear framework of 1 and 2 is quite similar; nevertheless, a comparison of the bismuth and oxygen atom positions of 1 and 2 shows a weighted root mean square deviation of 0.307 and 0.413 Å, respectively, as a result of the different coordination sphere. Both [Bi38O45]24+ cores in 1 and 2 are coordinated by two different anionic ligands with a ligand-to-ligand ratio of 22:2, which might indicate two particularly reactive positions at each bismuth oxido cluster
