FERROMAGNETIC INTERACTION BETWEEN GADOLINIUM(Ⅲ) AND COPPER (Ⅱ)IONS IN N,N'-BIS(2-AMINOPROPYL)OXAMIDO COPPER(Ⅱ) BRIDGED BINUCLEAR Gd(Ⅲ)-Cu(Ⅱ) COMPLEX

Received Date: 9 May 1994

The heterobinuclear complex of formula Cu(oxap)Gd(phen)₂(ClO₄)₃ has been synthesized,where oxap denotes the N,N'-bis (2-aminopropyl) oxamido dianion and phen represents 1,10-phenanthroline.The complex was characterized with ESR and variable temperature magnetic susceptibility (4-300K).The least-squares fit of the experimental susceptibilities yielded J=2.25cm^-1.The observed Gd(Ⅲ)-Cu(Ⅱ) coupling is ferromagnetic.One plausible mechanism that can cause a ferromagnetic coupling between Gd(Ⅲ) and Cu (Ⅱ) is discussed in terms of spin-polarization.
