| Popis: | Three β–diketonate mononuclear Ln-based compounds, formulated as [Tb III (hfac) 3 (dmbpy)]( 1 ), [Dy III (hfac) 3 (dmbpy)]( 2 ) and [Er III (hfac) 3 (dmbpy)]( 3 ) (hfac = hexafluoroacetylacetone, dmbpy = 4,4′-dimethyl-2,2′-dipyridyl) have been synthesized and structurally characterized by single crystal X-ray diffraction. Structure characterization reveals that complexes 1, 2 and 3 are isomorphous. Shape measurement shows the coordination geometry of complex 2 is trigonal dodecahedron (D 2d ). Magnetic property study indicates complex 2 shows SIM behavior with observed frequency-dependent signals at low temperature. |
