Figure 3
Crystal structure of TFA form II, showing the hydrogen-bond network (red dotted lines) and the deformation of the electron density calculated by TONTO (Capelli et al., 2014  ). Negative electron density is shown with green surfaces and positive electron density is shown with red (threshold level −0.25, Res/Å). Ellipsoids of carbon atoms are shown in grey, nitrogen blue, oxygen red, hydrogen white and chlorine green. |
