摘要：

The deprotonation in basic ethanolic solution of the 26 membered pyrazole derived macrocyclic Schiff base 1 and polyamine 3 affords dipyrazolate salts (1' and 3') from which dinuclear Cu(II) complexes (2 and 4) have been obtained. The Xray crystallographic analysis of 4 demonstrates that inside the macrocyclic cavity, the two pyrazolate rings are simultaneously acting as exobidentate ligands linking both metal cations, the Cu-Cu separation being 3.9 Angstrom.
