Abstract
Starting from a molecular cubane [Cu4L4] (1, with LH2 = 1,1,1-trifluoro-7-hydroxy-4-methyl-5-aza-hept-3-en-2-one), we successfully replaced one and then two copper(II) ions of the cubane core by lanthanide ions to elaborate new families of 3d−4f complexes. Here, we report the syntheses, crystal structures, magnetic properties, and theoretical description of the tetranuclear copper(II) complex [Cu4L4] (1, [Cu4]) together with original yttrium(III) and gadolinium(III) heterometallic derivatives:  [YCu3L3(hfac)3]- (2, [YCu3]); [GdCu3L3(hfac)3]- (3, [GdCu3]); [Y3Cu6L6(OH)6(MeOH)6(H2O)6]3+ (4, [Y3Cu6]); [Gd3Cu6L6(OH)6(MeOH)6(H2O)6]3+ (5, [Gd3Cu6]). 1 crystallizes in ...
