摘要：

Two iso structural lanthanide complexes, [Tb(salen)(2)](3)center dot 3C(2)H(9)N(2)center dot 4CH(4)O (1) and [Er(salen)(2)](3)center dot 3C(2)H(9)N(2)center dot 2CH(4)O (2), where H(2)salen = N,N '-bis(3-methoxys alicylidene)ethylene-1,2-diamine, have been in situ synthesized under solvothermal conditions and characterized by IR, elemental analysis, powder and single-crystal X-ray diffraction analysis, and magnetic analysis. Single-crystal X-ray diffraction indicates that the complexes crystallize in monoclinic C-121 space group. Each lanthanide center is coordinated with four oxygen and four nitrogen atoms from two salen 2-ligands, forming distorted square antiprism geometry. Both 1 and 2 exhibit obvious slow magnetization relaxation under an applied 2 kOe magnetic field.
