Figure 1
Ellipsoid plots of the components of the crystal structures. In the event of disorder, only the major component is illustrated, except in the case of (V) [part (e)]. A and B denote major and minor components, respectively. The displacement ellipsoids are at the 50% probability level. (a) DL-argininium DL-hydrogen tartrate (I), (b) bis(L-argininium) L-tartrate (II), (c) bis(DL-lysinium) DL-tartrate monohydrate (III), (d) L-lysinium D-hydrogen tartrate (IV) and (e) L-lysinium L-hydrogen tartrate (V). |
