Two Ag(I) complexes, namely [Ag 2 (L1) 2 (HMIP) 2 ·H 2 O] n ( 1 ) and [Ag 2 (L2) 2 (HPA) 2 ] n ( 2 ) (L1 = 1,6-bis(2-methylbenzimidazol-1-yl)hexane, L2 = 1,6-bis(benzimidazol-1-yl)hexane, H 2 MIP = 5-methylisophthalic acid, H 2 PA = phthalic acid), were hydrothermally synthesized and characterized by physicochemical and spectroscopic methods. 1 Processes a binuclear Ag(I) structure which is further extended into a 2D supramolecular network by hydrogen bonds and π – π stacking interactions. 2 Features a 1D meandering chain which is linked into a 3D supramolecular network by Ag···O and π – π stacking interactions. Complex 1 is shown to be a highly sensitive material for luminescence detecting Fe 3+ in aqueous solution. These complexes display high photocatalytic activities for degradation of methylene blue under UV irradiation.
