摘要：

The amide-substituted unsymmetrical ligand L-1 upon coordination to Co2+ forms the dinuclear triple helicate [Co-2(L-1)(3)](4+) which exists as both possible C-1 and C-3 symmetric geometric isomers in solution, however, upon addition of nitrate ions, the formation of an anion binding cavity is favoured and hence the sole product is the C-3 symmetric isomer in which all three amide substituents are hydrogen bonded to the nitrate anion.
