Electronic structure of 5,7,12,14-tetramethyl-1,4,8,11-tetra-azacyclotetradeca-2,4,6,9,11,13-hexaenato–nickel(II) cation radical, the central member of a ligand-based electron-transfer series

Abstract

The e.s.r. spectra of the title complex and four deuteriated derivatives exhibit well resolved hyperfine splittings which have been analysed in terms of a ²B_1u ground state with extensive ligand delocalization of the odd electron.
