Abstract

A new hydrazone-based Schiff base ligand, (E)-N′-(2-hydroxy-3-methoxy-5-methylbenzylidene)nicotinohydrazide (H2L), has been employed for the synthesis of a family of four dinuclear Dy(III) complexes, Dy2(L)2(OAc)2(H2O)2∙H2O (1), Dy2(L)(dbm)2(CH3OH)2∙2CH2Cl2 (2), Dy2(L)(pnba)2(H2O)0.8(CH3OH)1.2∙2H2O∙2.8CH3OH (3), and Dy2(L)2(mnba)2(H2O)2(CH3OH)2∙2CH3OH...
