Abstract

The nickel and zinc complexes of 2-aminomethylaniline (AMA) are reported. Both metals form the octahedral complex [M(AMA)(2)(ONO2)(2)] (M = Ni, Zn) where the aromatic ligands lie in the meridial plane with the anilino donors trans to one another. The remaining nitrates coordinate axially. A simple comparison with the nitrogen donor disposition (cis/trans) in nickel complexes of tetradentate N-4 donor ligands derived from symmetric Schiff base ligands is presented. The discussion is extended to interrogate the bonding motifs of the nitrate ligands viz -ONO2 in the nickel complexes of AMA compared to the two motifs (viz O2NO and ONO2) that are isolated for the nickel complexes of the macrocycle hexamethyltetraazacyclotetradecane.
