Reaction of nickel(II) with 5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradeca-4,11-diene diperchlorate in the presence of ammonia yields a lilac- coloured complex of nickel(II) with 13-imino-4,4,6,11,11-pentamethyl-3,7,10-triazatetradec-6-en-1-amine, a pentadentate ligand with one primary and two secondary amino, plus one primary and one secondary imino , donor groups. The copper(II) complex of the ligand was formed from the nickel(II) compound by metal-ion substitution. The cations have d-d spectra indicative of five-coordination. The complex cations undergo a reversible protonation reaction with a change from five-coordinate to square planar, with a colour change for nickel(II) from lilac (triplet ground state) to yellow (singlet ground state), and for copper(II) from blue to violet. The compounds of the homologous ligand 4,6,11-triethyl-13-imino-4,11- dimethyl-3,7,10-triazapentadec-6-en-1-amine were similarly prepared, and have similar properties.
