K. Udaya Lakshmi, S. Thamotharan, K. Ramamurthi and B. Varghese

Abstract: In the crystal structure of the title compound, 2C₃H₇N₆⁺·C₄H₄O₆^2-·2.5H₂O, the melaminium ions form infinite tapes via N-HN hydrogen bonds. The tartrate anions, lying on twofold rotation axes, are arranged in linear arrays. The crystal packing is stabilized by an extensive net of hydrogen bonds leading to a supramolecular architecture.
