Notes:
Molecular-mechanics calculations of the sexidentate coordinated complexes of the pendant arm macrocyclic hexaamines trans- (L1) and cis-6,13-dimethyl-3,4,8,11-tetraazacyclotetradecane-6,13-diamine (L2) reveal that the trans-isomer shows a preference toward small metal ions, whereas the L2 may coordinate a wider range of metal ions without significant intramolecular strain. Conformational disorder in previously reported crystal structures of complexes of L1 is interpreted, and predictions for some, as yet, unknown complexes of L2 are made.
