Piperazine (pip) were reacted with benzoic acid (Hba) and different substituted benzoic acid, such as o-chlorobenzoic acid (Hocba), m-chlorobenzoic acid (Hmcba), p-chlorobenzoic acid (Hpcba), o-aminobenzoic acid (Hoaba), p-aminobenzoic acid (Hpaba), affording a series of compounds [H 2pip][ba]2 (1), [H2pip][ocba]2 (2), [H2pip][mcba]2 (3), [H2pip][pcba]2 (4), [H2pip][oaba]2 (5), and [H2pip][paba] 2 (6). Extensive N-H???O hydrogen bonds are found in 1-6, featuring different hydrogen-bonding motifs. Compounds 1-4 have two-dimensional layers stabilized by strong N-H???O hydrogen bonds, while compounds 5 and 6 exhibit one-dimensional ribbons formed by N-H???O hydrogen bonds. Moreover, in compound 6, the existence of water molecules extends the one-dimensional ribbons into a three-dimensional supramolecular structure via hydrogen bonds.
