2,2′-Dihydroxy-N,N′-(ethane-1,2-diyl)dibenzamide

Abstract

The asymmetric unit of the title compound, C16H16N2O4, contains one half-molecule, the whole molecule being generated by an inversion center located at the mid-point of the C—C bond of the central ethane group. An intramolecular O—H...O hydrogen bond forms an S(6) ring motif. In the crystal, molecules are connected via N—H...O hydrogen bonds, generating infinite chains along [1-10].
