2-hydroxymethyl-4-tert-butylphenol and 2-hydroxymethyl-4-isopropylphenol are isomorphous; they crystallize in the tetragonal system, space groupI41/a(No. 88); cell parameters area=b=25.205(4) Å, forc=6.705(2) Återt-butyl derivative anda=b=24.340(5) Å,c=6.471(1) Å for the isopropyl derivative. The structures were determined and refined usingShelx76. The respectiveRvalues are 0.068 and 0.076. Thetert-butyl substituent is disordered with two possible orientations. Intramolecular interactions are due to H bonds around the 4 a
