Abstract
The reaction of AgNO3 with combinations of 1,3-bis(4-pyridyl)propane (bpp) and 1,3,5-benzenetricarboxylic acid (H3btc) in aqueous alcohol/ammonia at room temperature produces crystals of {[Ag6(H2O)2(bpp)6] · (btc)2 · 25H2O} n (Ι). Single crystal X-ray diffraction analysis reveals that the complex Ι consists of 1D infinite cationic chains of [Ag(bpp)] n n+ and [Ag(H2O)(bpp)] n n+ which are further linked into the cation layer of [Ag(bpp)] n n+ by Ag···π interactions. The noncoordinated btc3− serves as template driving surrounding water molecules to aggregate into the anionic water layer. The neighboring anionic water layer and cationic layer were further alternately joined into a 3D sandwich-like framework by hydrogen bonding. In addition, the luminescent properties of Ι were investigated.
