Diethyl 2,2-bis(3,5-di-tert-butyl-4-hydroxybenzyl)malonate

Abstract

The title molecule, C37H56O6, possesses twofold symmetry, with the twofold axis passing through the quaternary C atom. In the crystal, neighbouring molecules are linked via O—H...O hydrogen bonds involving the phenol OH group and the carbonyl O atom, forming chains propagating in [101]. Within these chains, rings are formed with an R22(20) motif. There are also C—H...O interactions present within the rings.
