Abstract
One hundred and thirty-nine nickel complexes containing the 1,4,8,11-tetraazacyclotetradecane backbone were found in the Cambridge Structural Database. Cluster analysis was used to separate the structures according to their macrocyclic configurations, using their conformations as a separation criteria. The most commonly found configuration was the trans III configuration. The amount of trans I macrocycles relative to trans III macrocycles was found to be higher for square-planar complexes than octahedral ones. Molecular mechanical conformational searches were done for select structures found in the Cambridge Structural Database.
