1 Source of material

The compound was obtained using commercial 1-(4-carboxybutyl)-3-methyl-1H-imidazol-3-ium bromide through anion exchanging with potassium hexafluorophosphate. An amount of 0.01 mol 1-(4-carboxybutyl)-3-methyl-1H-imidazol-3-ium bromide, 0.01 mol potassium hexafluorophosphate and 10 mL distilled water were added to a 25 mL round-bottom flask. After being stirred by a magnetic stirrer for about 24 h, the mixture was transferred to a separatory funnel and extracted with 10 mL CH2Cl2, the organic phase was placed at room temperature and evaporated slow, finally the colorless crystals suitable for single crystal X-ray diffraction were obtained after about one week. 1H NMR (d-DMSO, 400 M) δ ppm: 9.905 (s, 1H), 7.742 (s, 1H), 7.680 (s, 1H), 4.164 (t, 2H), 3.839 (s, 3H), 2.256 (t, 2H), 1.797 (m, 2H), 1.459 (m, 2H).

2 Experimental details

All H atoms were located at their calculated positions, with O–H = 0.82 (carboxyl) Å and C–H = 0.92 (methylene), 0.93 (imidazole ring) or 0.96 (methyl) Å, and refined isotropically through a riding model, with U iso(H) = 1.5 U eq(O, C) for carboxyl and methyl H atoms and 1.2 U eq(C) for methylene H atoms. The hexafluorophosphate group is disordered over two positions with site occupancy ratio of 0.49:0.51 [3].

3 Comment

Ionic liquids (ILs) are the important functional materials, they can be applied in the industry and research fields of catalysis [4], extraction [5], liquid crystals and electrochemistry [6]. So focusing on the attentions from the researchers in decades, and many novel ILs with functional organics were designed and synthesized such as amino acid [7] and carboxylic acid [8]. In this work, the bromide anion of 1-(4-carboxybutyl)-3-methyl-1H-imidazol-3-ium bromide was exchanged by hexafluorophosphate group, then yielded hexafluorophosphate salt ionic liquid containing imidazole – carboxylic acid.

Single crystal X-ray diffraction clearly reveals that the Br− anions are completely substituted by hexafluorophosphate groups without residual Br− anions. In addition, there are no other guest molecules of solvents in the asymmetric unit of the structure. The carboxyl group connects imidazole ring by the twist-arrangement of four methylene groups. The bond distances between O atom and C atom are 1.254(6) and 1.289(5) Å for C5–O2 and C5–O1, respectively. They are close to each other, embodying the delocalized state for the C=O and C–O bonds of carboxyl, agreeing with others in the coordination polymer [9].

No classical hydrogen bonds exist in the structure of this compound. The hexafluorophosphate group and imidazole – carboxylic acid interact through C–H⋯F hydrogen bond with D or R2 2(8) style. On the other hand, two molecules of imidazole – carboxylic acid associate by O–H⋯O hydrogen bond R2 2(8) style from two carboxyls to form a dimer. Through those hydrogen bonds, the molecules are connected one by one to create a stable 3-dimensional network with ABAB fashion along b axis. The centroids distance between the centroid of one imidazole ring and the adjacent one is 8.878(8) Å, revealing that no π⋯π interactions are present in the crystals.
