Anhydrous ionic co-crystals of cyanuric acid with LiCl and NaCl

Anhydrous ionic co-crystals (ICCs) of cyanuric acid (CA) with sodium \nand lithium chlorides have been prepared by solid state \nmethods and structurally characterized from X-ray powder diffraction \ndata (XRPD). Complete encapsulation of the Li+Cl− ion pair by \nthe organic molecules is observed in CA·LiCl, while the solid-state \nsolvation of piles of Na+ cations in CA·NaCl results in the markedly \nincreased dissolution rate (ca. 5 times) and solubility (ca. 20 times) \nin water with respect to pure CA.
