Synthesis, characterization, and structure of dinuclear copper(I) and silver(I) complexes of ortho-functionalized 1,3-bis(aryl)triazenide ligands
摘要:
The synthesis, characterization, and crystal structures of dinuclear copper(l) and silver(l) complexes with a functionalized 1,3-diaryl triazenide ligand are reported. The triazene ligand is substituted with carboxymethyl groups in the ortho positions of the aryl rings that can coordinate to electron deficient metals. Reaction of this ligand with Cu(OAc) and Ag(OAc) resulted in the formation of dinuclear complexes with an eight-membered ring core composed of the two triazenide ligands and two metals. In these complexes, only one carbonyl group of each triazenide ligand binds to the metal centers. (C) 2003 Elsevier Science Ltd. All rights reserved.
