Figure 5
Experimental crystal structure of (XXV) at 300 K, showing the asymmetric unit and the unit cell; C atoms are in grey, H in white, O in red and N in blue. The proton is shown as originally refined at 300 K, attached to the carboxylic acid. Close analysis of the data and further data collected at 100 K suggest that a disordered structure with the H atom occupying two sites is more representative.
