摘要

Tetranuclear copper(II) complexes were obtained after simply dissolving [Cu(hfac)(2)] in formamide - methanol mixed solvents (Hhfac = 1,1,1,5,5,5-hexafluoropentane-2,4-dione). X-Ray diffraction studies revealed that they possessed a tetranuclear double half-cubane core sandwiched with two trianionic ligands from 2,4,6-tris(trifluoromethyl) tetrahydropyran-2,4,6-triol (H(3)ttpt). Complexes [Cu-4(ttpt)(2)(hfac)(2)(dmf)(2.5)], [Cu-4(ttpt)(2)(tfa)(2)(def)(4)], and [Cu-4(ttpt)(2)(hfac)(2)(H2O)(4)]( fa) were prepared from N,N-dimethylformamide(dmf) - MeOH, N, N-diethylformamide (def) -MeOH, and formamide(fa) - MeOH (Htfa = trifluoroacetic acid), respectively. A possible mechanism is proposed where a templated aldol-type reaction takes place between hfac and 1,1,1-trifluoroacetonate. Magnetic measurements revealed the presence of antiferromagnetic interaction in the Cu4O6 core.
