AbstractFive hexanuclear lanthanide clusters of composition [Ln(6)(mu(4)-O)(2)(HCOO) L-2(4)(HL')(2)(dmf())2] [Ln=Dy (1), Er (2), Ho (3), Tb (4), Gd (5); H2L=2-{[2-(hydroxymethyl)phenylimino]methyl}-6-methoxyphenol; H3L'=3-{[2-(hydroxymethyl)phenylimino] methyl} benzene-1,2-diol; H3L' was derived in situ from the H2L ligand] were prepared under solvothermal conditions. The [Ln(6)] cores of 1-5 possess an unprecedented motif, namely, two tetrahedron Ln(4) units sharing an edge and two vertices. The six Ln(III) ions of 1-5 are connected through two mu(4)-O anions. Magnetic susceptibility studies reveal that complex 1 exhibits frequency dependence of the alternating current susceptibility typical of single-molecule magnets. Complex 1 possesses a relatively large energy barrier of 85 K among all of the reported Dy-6 single-molecule magnets.
