| 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 N4 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. |
