Stereospecific ligands and their complexes. Part XIV. Crystal structure of the O,O′-dipropyl ester of N,N′-1,2-ethanediylbis-L-leucine, dihydrochloride

Abstract

The bidentate N,N′-ligand precursor, the O,O′-dipropyl ester of N, N′-1,2-ethanediylbis-L-leucine, dihydrochloride, [(S,S)-H 4eddl]Cl2, was prepared and its crystal structure is given herein. It crystallizes in a P42 space group of a tetragonal crystal system with a = 16.5620 (2) Å, b = 16.5620 (2) Å, c = 5.2240 (1) Å and Z = 2.
