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.
