A new series of mononuclear lanthanide single molecule magnets based on sandwich-type germanomolybdates, (C4H10ON)(8)H-5[Er(GeMo11O39)(2)]center dot 14H(2)O (1), (C4H10ON) H-8(5)[Gd(GeMo11O39)(2)]center dot 13H(2)O (2), (C4H10ON) H-8(5) [Dy(GeMo11O39) (2)]center dot 15H(2)O (3), (C4H10ON)(8)H-5[Tb(GeMo11O39)(2)]center dot 14H(2)O (4), have been successfully synthesized. Compounds 1-4 are the first examples of the coordination assembly of monolacunary germanomolybdates and heavy rare earth elements, and were structurally characterized by single-crystal X-ray diffraction analyses. The magnetic investigation shows that 1 and 3 exhibit magnetic relaxation behavior in a zero applied dc field, indicative of SMM behavior. Slow magnetic relaxation behavior of 1-4 could be observed in a static magnetic field of 5000 Oe.
