Figure 3
[R_4^4(16)] ring motifs in (a) L-cysteine-I at ambient pressure, (b) L-cysteine-I at 1.8 GPa, (c) L-cysteine-III at 2.6 GPa and (d) L-cysteine-IV at 1.7 GPa. (a)–(c) are viewed along b, while (d) is viewed along c. N—H⋯O and C—H⋯O hydrogen bonds are drawn as black and orange dotted lines, respectively, while S—H⋯O interactions in L-cysteine-III are depicted as green dotted lines. For clarity, all C—H⋯O and S⋯O interactions are drawn only in the top left quadrant. Colour scheme: yellow S, blue N, red O, grey C and dark grey H.
