Figure 4
(a) The mol­ecular structure of the asymmetric unit of IV, showing the atom-numbering scheme. The part with highest occupancy factors is shown as displacement ellipsoids (at the 50% probability level) and C-bound H atoms in the main mol­ecule have been omitted for clarity. (b) The supra­molecular layer formed via O—H⋯O hydrogen bonds. Comparison of the mol­ecular packing in the crystal of (c) IV and (d) the ortho­rhom­bic form of TrCOTyr. Hydrogen bonds are shown as dashed lines and N and O atoms are shown as balls.
