Source of material
Samples of 2,4,6-pyridine-tricarboxylic acid (0.25 mmol) and guanidine hydrochloride were separately dissolved in water-ethanol (50/100 v/v) according to a 1:3 molar ratio. Tetrapropylammonium hydroxide (30% solution, C. R.) was carefully added to obtain a solution with a 1:3 molar ratio of acid to hydroxide. The mixture was stirred for about 2 h and set aside to crystallize, finally yielding colorless block crystals suitable for single crystal X-ray diffraction.
Experimental details
The H atoms bonded to C were localized in the ideal positions and all H atoms bonded to O atoms were searched with Q peaks and refined with the O—H distance restrained to 0.86 Å. The Uiso values of the hydrogen atoms bonded to O were set to 1.5Ueq(O).
Discussion
2,4,6-Pyridine-tricarboxylic acid can be regarded as a triangular molecule that can form lots of various hydrogen bonds due to its carboxyl groups and the nitrogen atom. Under basic conditions, the planar acid tends to lose its protons to form a triangular anion that can act as a good hydrogen bond acceptor. The guanidinium cation is a triangular hydrogen bond donor. Thus, combining 2,4,6-pyridine-tricarboxylic acid with guanidinium under basic conditions should lead to the formation of interesting hydrogen-bonded frameworks. In the literatures, it was found that the acid and guanidine can generate different crystal structures with the existence of tetraalkylammonium hydroxides [4].
In the asymmetric unit of the title compound, there are three crystallographically independent 2,4,6-pyridine-tricarboxylate anions, three guanidinium cations, three tetrapropylammonium cations and ten water molecules. Obviously, after the total deprotonation of 2,4,6-pyridine-tricarboxylic acid. All bond lengths and angles are in the expected ranges [5]. The anions link with different triangular cations to form the complicated hydrogen-bonded framework which contains the ten water molecules. It is very clear that the anions are hydrogen-bond acceptors and the triangular cations are donors, and water molecules play crucial linkage roles in further constructing the 3-D framework with cavities that can contain tetrapropylammonium cations. Undoubtedly, N—H⋯O and O—H⋯O hydrogen bonds are important interactions in forming the stable crystal structure.
