Abstract

A new class of azolate ligands, deriving from the equimolar condensation of 3, 5-diamino-1, 2, 4-triazole with salicylaldehyde (H3L1) and o-anisaldehyde (H3L2) was prepared. In their anionic form, these species act as bridging moieties upon coordination to Cu (I) and Ag (I), giving rise to the formation of dinuclear complexes with the ligand in the typical N, N′- exobidentate conformation. The copper derivative [Cu (H2L1)(CH3CN)] 2 (1) showed ...
