A Neutral Dinuclear Silver(I) 4′-Phenyl-Terpyridine Compound

Abstract

A hydrothermal reaction between 4′-phenyl-terpyridine (L), silver(I) salt (silver nitrate), and disodium terephthalate led to the formation of the [Ag₂(μ₂-OCOC₆H₄OCO)L₂] complex. Its structure is determined by single crystal X-ray diffraction and confirmed by ¹H NMR and IR. The compound features a dinuclear neutral {Ag₂(μ₂-OCOC₆H₄OCO)} core in which each Ag⁺ ion is coordinated by three nitrogen atoms from the terpyridine ligand and one oxygen atom from the carboxylic group of terephthalate, forming an irregular AgN₃O square coordination geometry with a separation of 11.3301(5) Å between the two silver ions.
