Abstract

Two unusual metal–organic frameworks {[Ag2(Hbtc)(bpy)2]·(H2O)2}n (1), {[Ag3(btc)(bpy)3(H2O)]·(H2O)7}n (2) (H3btc = 1,2,3-benzenetricarboxylic acid, bpy = 4,4′-bipyridine) have been synthesized and characterized by single crystal X-ray diffraction. Complex 1 features an infinite 1D→1D tubular intertwinement network, while complex 2 exhibits a double ladder structure which contains rare winding water chains. Both infinite 1D→1D tubular chains in complex 1 and double ladder in 2 are mutually interconnected by hydrogen bonding and π⋯π stacking interactions into three-dimensional (3D) supramolecular networks. In addition, thermogravimetric analysis, powder X-ray diffraction (XRD), and photoluminescent behavior of the complexes have also been investigated.
