  摘要：

  The reaction of N,N'-ethylenebis(salicylideneiminato)diaquochromium(III) chloride, [Cr(salen)(H2O)2]Cl, with bis(1,1,1,5,5,5-hexafluoro-2,4-pentanedionato)diaquameta](II), M(hfa)2(H2O)2 (M=Cu, Ni or Co), in aqueous ethanol results in the isolation of dinuclear complexes, [Cr(salen)(solvent)2M(hfa)2]Cl. The compounds are characterized by IR and UV-Vis spectroscopy and variable temperature magnetic susceptibility. The Cr(III)-Cu(II) complex is ferromagnetically coupled with J=9.7 cm-1 and the Cr(III)-Ni(II) and Cr(III)-Co(II) complexes are antiferromagnetically coupled with J=-11.3 and -6.7 cm-1, respectively. The analogous reactions with Fe(hfa)2 and Mn(hfa)2(H2O)2 do not yield dinuclear complexes. The former gives electron transfer products and the latter, the anion exchange product, Cr(salen)(hfa). The analogous reactions of Fe(salen)Cl with M(hfa)2 (M=Cu, Ni, Co, or Mn) result in the formation of Fe(salen)(hfa) (M=Co, Ni or Mn) and Cu(salen) (M=Cu).
