Abstract

A series of NS3-open chain and cage ligands were synthesised and their complexation behaviour towards Ag (I) and Cu (I) studied. Crystal structures show that all open chain ligands form complexes in which the four donor atoms of the ligands coordinate the metal ions in a trigonal pyramidal geometry. For the NS3-cages, however, the ions are not in the centre of the cage, but show peripheral coordination resulting in polymeric crystal ...
