• Among several basic amino acids, only the L-lysine free base was found to form a crystalline salt with inosine. A specific stereochemical arrangement of these two molecules, inosine and L-lysine, is considered to be involved in such a crystalline salt-formation on the basis of the fact that D-lysine did not form a crystalline salt with inosine. Part of the equilibria were determined at 10 °C for the inosine–L-lysine–water and inosine–L-lysine-60 w/w % aqueous ethanol systems. The salt was unstable against water, while it was stable against aqueous ethanol (containing more than about 40% ethanol). The solubility of the salt in water was summarized as follows: log<I>S</I> (w/w %) =0.0219<I>t</I>+0.624. The X-ray powder diffraction data of the salt are given.
