A new three dimensional proton transfer compound including citric acid and 2,4,6-triamine-1,3,5-triazine: synthesis, characterization and X-ray crystal structure

A new three dimensional proton transfer compound, (tataH)2(citH).2H2O (I) was synthesized from the reaction of citric acid (citH3), and 2,4,6-triamino-1,3,5-triazine (tata). The characterization was performed using elemental analysis, IR spectroscopy, and single crystal X-ray structure determination. The crystal structure of the title compound consists of bis-2,4,6-triamino-1,3,5-triazin-1-ium cations, hydrogen citrate, and lattice water molecules. Intermolecular O-H O, N-H O, and N-H N hydrogen bonding interactions stabilize the crystal structure. The hydrogen bonds distances range from of 1.781 to 2.088 . The π-π stacking (centroid-centroid ranges 3.410-3.504 ) between two aromatic rings of tata moieties can play an essential role in the creation and stabilization of the title crystalline network.
