N-[(1S,2S)-2-Amino-1,2-diphenylethyl]-4-methylbenzenesulfonamide[(S,S)-TsDPEN]

The crystal structure of the title compound, C21H22N2O2S, shows a network of N-H center dot center dot center dot N and N-H center dot center dot center dot O hydrogen bonds. The tolyl and 1-phenyl rings are almost mutually coplanar [7.89 (9)degrees], while the 2-phenyl ring makes a dihedral angle of 50.8 (1)degrees with the 1-phenyl ring. An intramolecular N-H center dot center dot center dot N hydrogen bond stabilizes the molecular conformation
