Abstract
The title compound N,N-bis(2-oxopyrrolidin-1-ylmethyl)leucine (PML) has bee n prepared, and its crystal structure was determined by single crystal X-ra y diffraction. The molecule has four conformations differing from each othe r in the corresponding bond lengths and angles, which may arise from steric effect of the bulky groups. The europium(III) complex with PML and 1,10-ph enanthroline(phen) has photochromic reactivity in aqueous medium, which was studied spectroscopically. (C) 2000 Elsevier Science B.V.
