N,O‐Bidentate Schiff Bases as Novel Ligands and Self‐Assembled Three‐Dimensional Supramolecular Complex of Silver(I): Syntheses and Characterization

Abstract

Three novel N,O‐bidentate Schiff bases H₂L¹, H₂L², and H₂L³ have been prepared and investigated. H₂L¹ underwent self‐assembly with silver(I) nitrate forming the supramolecular complex [Ag₂(H₂L¹)₃] _n (NO₃)_2n , whereas H₂L² and H₂L³ do not form supramolecular complexes due to the chain length of the bidentate Schiff bases, which prevent Ag–N interactions. The results indicate the effect of the chain length of diamine, the presence of active phenol group, and the arrangement of silver(I) interactions on the formation of three‐dimensional (3D) supramolecular complex.
