摘　　要：The assembly reactions of o- （or m-, or p-） tetrafluorobenzenedicarboxylic acid （denoted as o-H2L, m-H2L and p-HzL, respectively）, benzonitrile and Ag＋ ion led to three compounds： [Ag2（PhCN）2（o-HL）2]n （1）, [Ag2（PhCN）2（m-HL）2]n （2） and [Ag2（PhCN）2（p-L）], （3）. 1 and 2 feature a 1D coordination chain, while 3 bears a 2D net structure. A variety of weak interactions are observed in the compounds. Strong nwrinteractions connect the 1D chains into a 3D supramolecular network in 1. Hydrogen bonds connect the chains into layers in 2. Three types of interesting π-π interactions also assemble the 2D layers into a 3D overall structure in 3.The assembly reactions of o- （or m-, or p-） tetrafluorobenzenedicarboxylic acid （denoted as o-H2L, m-H2L and p-HzL, respectively）, benzonitrile and Ag＋ ion led to three compounds： [Ag2（PhCN）2（o-HL）2]n （1）, [Ag2（PhCN）2（m-HL）2]n （2） and [Ag2（PhCN）2（p-L）], （3）. 1 and 2 feature a 1D coordination chain, while 3 bears a 2D net structure.
