Hydrogen-bonded networks in 1-(4-methoxy­phen­yl)-2,2-dimethyl­propan-1-ol

The asymmetric unit of the title compound, C₁₂H₁₈O₂, contains two independent mol­ecules. They differ only slightly in conformation but form completely different inter­molecular hydrogen-bonded arrays. One molecule exhibits disorder in the hydroxy group region, but this does not influence the formation of hydrogen bonds. The bulky tert-butyl group on one side of the carbinol C atom and the benzene ring on the other side promote the formation of discrete dimeric motifs via hydrogen-bridged hydroxy groups. Dimers are further joined by strong hydroxy–methoxy O—H...O bonds to form chains with dangling alcohol groups. Weaker inter­molecular C—H...O inter­actions mediate the formation of a two-dimensional network.
