Abstract
Eight 3d-4f heterometallic complexes were successfully yielded by the solvothermal reactions of Ln(NO3)3·nH2O, Co(NO3)2·6H2O, 2,3-dichlorobenzoic acid (2,3-HDCB), NaOH and 2,2′-bipyridine (2,2′-bpy), namely [Ln2Co2(2,3-DCB)10(2,2′-bpy)2] [Ln = Nd (1), Sm (2), Eu (3), Gd (4), Tb (5), Dy (6), Er (7) and Yb (8)]. These eight complexes were characterized by single-crystal X-ray diffraction, FT-IR spectrum, powder X-ray diffraction (PXRD) and thermogravimetric analysis (TGA). They show isomorphous zero-dimensional (0D) linear tetranuclear cluster structures. Their magnetic properties were investigated.
