Figure 1
The asymmetric unit of (I)[link], solvent mol­ecules being shown in different positions relative to the peptide mol­ecules than they have in the unit cell to avoid extensive overlap. The minor disorder orientation for TFE mol­ecule D is shown in wireframe representation. The amino group of mol­ecule A has an unusual eclipsed conformation (blue shade) resulting from formation of an intra­molecular hydrogen bond to O1A, while a normal staggered conformation (red shade) is observed for mol­ecule B. Thermal displacement ellipsoids are shown at the 50% probability level.
