Figure 6
Visualization of the anisotropy of the compressibility under hydrostatic compression for β-glycine. The yellow axis corresponds to the direction of minimum hydrostatic compressibility, the cyan axis corresponds to maximum hydrostatic compressibility. Pink, red, green and blue colors of dotted lines correspond to hydrogen bonds I, II, III and IV, respectively. Symmetrically non-equivalent glycine molecules are colored green and red. Symmetry codes of acceptors in hydrogen bonds: (I) −x, y + ½, −z; (II) x, y, z − 1, (III) −x, y + ½, −z; (IV) −x, y + ½, −z + 1. |
