Abstract

Two salen type heteronuclear Cu-Gd complexes, namely, [(GdCuL ¹Cl₃(CH₃OH)₂] (1) and [Gd ₂Cu₄L²₄Cl₂(OH)](PF ₆)₃ (2) (H₂L¹ = N,N′-bis(2- hydroxy-3-methoxybenzylidene)-1,2-diaminocyclohexane and H₂L ² = N,N′-bis(2-hydroxy-3-methoxybenzylidene)-1,3- diaminopropane) have been isolated. X-ray crystallographic analysis shows that 1 is of a typical neutral heterodinuclear Cu-Gd structure, while 2 features an unusual ionic hexanuclear Cu-Gd structure. Magnetic analysis reveals the dominant ferromagnetic interactions within the clusters.
