The angle between the benzene ring and the mean plane of the formamide group is 71.1 (1)°. The amide groups of neighbouring mol­ecules are connected by N—H(...)O hydrogen bonds, forming 21 helical chains propagating along [001]. Mol­ecules are also connected by weak inter­molecular C—H(...)O hydrogen bonds, forming 61 helices. Matthias Berger; Jan W.

In the crystal, mol­ecules are connected by O—H[cdots, three dots, centered]N hydrogen bonds, forming zigzag chains along the c-axis direction. The chains are connected by bifurcated N—H[cdots, three dots, centered](N,N) hydrogen bonds into layers parallel to (100). These layers are connected along the a-axis direction by weak C—H[cdots, three dots, centered]O contacts, forming a three-dimensional network. Abdelaaziz Ouahrouch; Moha Taourirte; Hassan B.
