Two nanosized Mn49 and Mn25Na4 clusters based on analogues of the high-spin (S=22) [MnIII 6MnII 4(μ4-O)4]18+ supertetrahedral core are reported. Mn49 and Mn25Na4 complexes consist of eight and four decametallic supertetrahedral subunits, respectively, display high virtual symmetry (Oh), and are unique examples of clusters based on a large number of tightly linked high nuclearity magnetic units. The complexes also have large spin ground-state values (Mn49: S=61/2 Mn25Na4: S=51/2) with the Mn49 cluster displaying single-molecule magnet (SMM) behavior and being the second largest reported homometallic SMM. © 2016 Wiley-VCH Verlag GmbH & Co.
