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].
