Novel dinuclear copper(II) complexes were synthesized by the reaction of copper(II) chloride dihydrate with one ancillary ligand, either 2,2':6',2''-terpyridine, 4'-chloro-2,2':6',2''-terpyridine or 2,6-bis(2-benzimidazolyl)pyridine, followed by the addition of silver triflate and a bridging ligand…
