Understanding the process of the self‐assembly of gigantic polyoxometalates and their subsequent molecular growth, by the addition of capping moieties onto the oxo‐frameworks, is critical for the development of the designed assembly of complex high‐nuclearity cluster species, yet such processes remain far from being understood. Herein we describe the molecular growth from {Mo 150 } and {Mo 120 Ce 6 } to afford two half‐closed gigantic molybdenum blue clusters {Mo 180 } ( 1 ) and {Mo 130 Ce 6 } ( 2 ), respectively. Compound 1 features a hat‐shaped structure with the parent wheel‐shaped {Mo 150 } being capped by a {Mo 30 } unit on one side. Similarly, 2 exhibits an elliptical lanthanide‐doped wheel {Mo 120 Ce 6 } that is sealed by a {Mo 10 } unit on one side. Moreover, the observation of the parent uncapped {Mo 150 } and {Mo 120 Ce 6 } clusters as minor products during the synthesis of 1 and 2 strongly suggests that the molecular growth process can be initialized from {Mo 150 } and {Mo 120 Ce 6 } in solution, respectively.
