Figure 2
Electrostatic potentials plotted onto electron-density isosurfaces of 0.5 e Å−3 for (a) tetrachloroquinone (Molčanov et al., 2019BB53), (b) neutral chloranilic acid (Vuković et al., 2019BB105) and (c) the hydrogen chloranilate monoanion (Molčanov et al., 2015BB67). The electrostatic potentials range from −0.1 e Å−1 (red) to 1.0 e Å−1 (dark blue). Alternating electron-rich and electron-depleted areas can be observed.
