Abstract
A new cyclam with a pendant primary amino donor, 6-amino-1,4,8,1,1-tetraraazacyclotetradecane, 3, has been synthesized from diethyl aminomalonate and 1,9-diamino-3,7-diazanonane in refluxing MeOH, followed by BH 3 .THF reduction. Reaction of 3 with Ni(ClO 4 ) 2 .6H 2 O in a pH 8.5 aqueous solution yielded a Ni II complex 14, whise X-ray crystal structure has shown that the pendant NH 2 axially coordinates to Ni II and the cyclam moiety takes a trans I configuration.
