4'-Hydroxybiphenyl-4-carbonitrile.
The title compound, C13H9NO, crystallizes with four molecules in the asymmetric unit. Each of the four crystallographically independent molecules forms a chain parallel to the a axis with symmetry-equivalent molecules. These chains are held together by similar O-H...NC hydrogen bonds, with approximately linear O-H...N angles and significantly bent H...N-C angles. The four different molecules are related by strong elements of pseudosymmetry. To better describe the pseudosymmetry, the structure has been reported in the non-standard space group C-1.
