Ion pair complexes form the reduction of metal(II)-dibenzotetramethyltetra-aza[14]annulene complexes

Abstract

Ion pair complexes, [M(tmtaa)Na(thf)₃](M = Fe, Co, or Ni; tmtaa = dibenzotetramethyltetra-aza[14]annulene dianion; thf = tetrahydrofuran), in which both metal ions are associated with the macrocyclic ligand have been obtained form single-electron reduction of the parent metal(II) compounds with sodium metal; the crystal structure of one of the complexes is reported.
