- General one-step self-assembly of isostructural intermetallic Co II3LnIII Cubane Aggregates
-
A new family of Co/rare-earth intermetallic cubane aggregates [Co 3Ln(hmp)4(OAc)5H2O] (Ln = Dy, Ho, Er, Tm, Yb, Y) have been synthesized by self-assembly. Single-crystal X-ray diffraction analysis revealed that they are remarkably isostructural in showing a common [Co3Ln] core. Magnetic studies showed that the Dy, Er, Tm, Yb, and Y complexes are ferromagnetic. The Dy complex exhibits the largest magnetocaloric effect (-ΔSm = 12.58 J kg-1 K -1), which can be attributed to the large magnetic density of Dy III.
