Silver(I) Coordination Complexes of 1,10-Phenanthroline-5,6-dione with 1D Chain and 2D Network Structure

Abstract

Two silver(I) coordination complexes of 1,10-phenanthroline-5,6-dione (pdon), [Ag2(pdon)2(ClO4)2] ( 1 ) and [Ag(pdon)2](CF3SO3) ( 2 ), have been synthesized and characterized by elemental analysis, IR, and X-ray diffraction analysis. Using AgClO4 with pdon, the central silver(I) is bridged by ligand pdon with two N and one O atoms and lead to the one-dimensional (1D) chain structure in 1 . When triflate anion is used as a counter ion in 2 , the silver(I) is chelated by two ligands with four N atoms, and then the molecular unit is linked by intermolecular hydrogen bond to afford a novel two-dimensional (2D) network architecture.
