New Family of Heptanuclear Lanthanide {Ln7} Clusters: Synthesis, Structure, and Magnetic Studies

摘要

A new family of heptanuclear lanthanide complex [Ln7(L)2(LH)4(dbm)5(OH)2(CH3OH)4]?xCHCl3?yCH3OH?zH2O {Ln= TbIII (1), DyIII (2) and Er III (3) and LH3 =(E)-2-(hydroxymethyl)-6- (((2-hydroxyphenyl) imino) methyl)-4-methylphenol} [in 1, x=6, y=3, z=3; in 2, x=5, y=1, z=6; and in 3, x=4, z=2] has been prepared in presence of lanthanide chloride(III) salts and β-diketonate co-ligand dibenzoylmethane (dbm).
