Abstract

A new dysprosium(III)-nickel(II) heterometallic cluster, namely, [Dy ₃ IIINi₄ II(L)₆ (OH)₄ (CH ₃OH)₃(CH₃CN) (NO₃)(OH ₂)]·(CH₃CN)₃ (CH₃OH) ₂ (H₂O)₂ (1), has been synthesized from the schiff-base ligand H2L (L = o-phenolsalicylimine), dysprosium nitrate and nickel nitrate. A singlecrystal X-ray diffraction study reveals that the highly asymmetric core of 1 consists of an unprecedented edgesharing arrangement of three dissimilarDy₂Ni triangles, along with oneDy₂Ni ₂ rectangle, connected to one side of the central metallic core. Both static (dc) and dynamic (ac) magnetic properties of 1 have been studied. The results reveal that compound 1 exhibits slow relaxation of the magnetization, making 1 a remarkable new addition to the family of Ln-Ni single molecule magnets, having a new asymmetric Ni4Dy3-architecture.
