Two classes of Ni-Ln clusters [Ln(4)Ni(3)L(3)( OAc)(6)( NO3)(3)(OH)(3)] (Ln = Gd (1) and Tb (2)) and [ Ln(6)Ni7L(6)(OAc)(12)(OH)(6)](OH)(2) (Ln = Gd (3) and Dy ( 4)) were prepared using a specifically designed Schiff base ligand built around a flexible (CH2)(2)O( CH2)(2)O(CH2)(2) chain. 1 and 2 exhibit cone-like structures, while 3 and 4 have nanosized sandwich architectures. The structures were studied by single-crystal X-ray diffraction and TEM, and magnetic properties were investigated.
