M. Handa et al., Dinuclear phenoxo-bridged nickel(II) complexes of macrocyclic ligands withcyano groups laterally introduced on a conjugated system within the ligands, MOLEC CRYST, 342, 2000, pp. 75-80
Diphenoxo-bridged dinuclear nickel(II) complexes of macrocyclic ligands hav
ing two cyano groups laterally introduced on a pi-conjugated system within
the ligands have bean prepared and characterized. The reaction solvent DMF
is coordinated to the nickel(II) ions to cause them high spin state. The an
tiferromagnetic interaction (J = ca. -10 cm(-1)) was observed between the n
ickel(II) ions.
