(S)-2,2'-Dihydroxy-N,N'-(6-hydroxyhexane-1,5-diyl)dibenzamide

S. Wilbrand, C. Neis and K. Hegetschweiler

Abstract: In the title compound, C20H24N2O5, the dihedral angle between the two roughly planar salicylamide fragments [r.m.s. deviations = 0.043 (2) and 0.149 (2) Å] is 25.50 (5)°. The molecular conformation is stabilized by intramolecular O-H...O hydrogen bonds involving phenol -OH groups and amide O atoms. Intermolecular hydroxymethyl-amide O-H...O and amine-hydroxymethyl N-H...O hydrogen bonds form infinite chains along the b axis. These chains are further interlinked by amine-amide N-H...O and phenol-phenol O-H...O interactions, thus giving layers parallel to (001).
