Dinuclear Phenoxo-Bridged Nickel(II) Complexes of Macrocyclic Ligands with Cyano Groups Laterally Introduced on a Conjugated System

摘要

Diphenoxo-bridged dinuclear nickel (II) complexes of macrocyclic ligands having two cyano groups laterally introduced on a #pi#-conjugated system within the ligands have been prepared and characterized. The reaction solvent DMF is coordinated to the nickel(II) ions to cause them high spin state. The antiferromagnetic interaction (J = ca. -10 cm~(-1)) was observed between the nickel(II) ions.
