Abstract

A new series of mononuclear lanthanide single molecule magnets based on sandwich-type germanomolybdates, (C4H10ON)8H5[Er(GeMo11O39)2]·14H2O (1), (C4H10ON)8H5[Gd(GeMo11O39)2]·13H2O (2), (C4H10ON)8H5 [Dy(GeMo11O39)2]·15H2O (3), (C4H10ON)8H5[Tb(GeMo11O39)2]·14H2O (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.
