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.
