A solved structure: The hydrated Ga13 cluster, [Ga133-OH)6(μ-OH)18(H2O)24](NO3)15], persists as a discrete nanoscale structure in an aqueous polar solvent at millimolar concentration. SAXS data confirm the presence of Ga13 in dimethyl sulfoxide (DMSO). In aqueous [D6]DMSO 1H NMR signals for the hydroxo and aquo ligands of Ga13 were detected, thus showing a cluster with a hydrodynamic radius of (11.2±0.8) Å (see picture).
