Multi-component synthesis of trimetallic tetranuclear clusters [Cu(L)(H2O)]2Ln(H2O)2Cr(C2O4)3·12H2O (H2L = 1,4,8,11-tetraazacyclotradecane-2,3-dione, Ln3+ = Gd, Tb and Dy)

Abstract

Novel tetranuclear Cu(II)Ln(III)Cr(III) complexes with oxamidate and oxalate bridges have been prepared using [Cu(L)], LnCl3·6H2O and K3[Cr(ox)3] components (ox2− = oxalate) during the development of new multimetallic complexes as molecular magnets. Overall ferromagnetic properties have been observed in the Cu2GdCr compound, and no single-magnet behavior has been found in the Cu2TbCr and Cu2DyCr compounds.
