SILVER(I) SILVER(I) INTERACTIONS IN COMPLEXES OF PENTADENTATE MACROCYCLIC LIGANDS - CRYSTAL AND MOLECULAR-STRUCTURE OF [AG2L2][BF4]2 (L=1,11-BIS(2'-HYDROXYETHYL)-4,8-12,16-17,21-TRINITRILO-1,2,10,11-TETRAAZACYCLOHENICOSA-2,4,6,9,12,14,18,20-OCTAENE)

Silver(I) ions do not act as templates for the formation of planar macrocyclic ligands based upon 2,2'-bipyridine or 1,10-phenanthroline, but incorporation of silver(I) into the performed macrocycles, obtained from transient template reactions, is facile. The complexes so obtained have a 1:1 ratio of silver to macrocycle. The crystal structure of the complex [Ag2L2][BF4]2 reveals a dimeric structure in the solid state with two distinct silver environments.
