Covalent grafting of “organic caps” onto Dawson metal oxide clusters controls their supramolecular self-assembly in the solid and solution phase. Formation can be controlled by changing the solvent and the hydrogen-bonding groups on the cap. A gigantic nanoassembly with a mass of ca. 21 kDa is characterized unambiguously in the solid state using single-crystal XRD, and detected in solution/gas phase by cryospray mass spectrometry as the 5 ion.
