Two Keggin Fe-oxo clusters, [PrFe(NO)(L-van)(D-van)(TEOA)(μ-OH)(μ-OH)(μ-O)(HO)]·(ClO)·(NO)·10HO () and [DyFe(NO)(L-van)(D-van)(TEOA)(μ-OH)(μ-OH)(μ-O)(HO)]·(ClO)·(NO)·15HO (), where L-van = l-valine, D-van = d-valine, and TEOA = triethanolamine, were prepared by using Ln as a stabilizer. Cluster crystallizes in a chiral space group of 2, while cluster crystallizes in a centrosymmetric space group of . Dynamic magnetic measurements of under a zero direct-current field reveal that exhibits single-molecule-magnet characteristics with an energy barrier of 18.79 K. Significantly, the formation of the chiral cluster is closely related to the larger radius of the Pr ion.
