Abstract

The planar form of the complex C-meso-1,4,5,7,7,8,11,12,14,14-decamethyl-1, 4,8,11 - tetra-azacyclotetradecanenickel(I) {[Ni(L¹)]⁺} is shown to be stable in aqueous solutions, with t_1/2 > 100 h and the formal potential of the couple [Ni(L¹)]²⁺/[Ni(L ¹)]⁺ is -0.98 V vs. standard calomel electrode; redox reactions involving this couple were studied and compared with those of the couple [Ni(L²)]²⁺/[Ni(L²)]⁺ (L ² = C-meso-5,7,7,12,14,14-hexamethyl-1,4,8,11-tetra- azacyclotetradecane).
