Abstract
5,5'-Di-tert-butyl-2,2'-dihydroxy-3,3'-methanediyldibenzaldehyde, C(23)H(28)O(4), (IV), has been structurally characterized in two polymorphic forms. The tetragonal form, (in I4(1)/a) has been reported previously but is redetermined and reinterpreted here, while the monoclinic form, (in C2/c) is reported for the first time. In both polymorphs, the molecule lies on a crystallographic twofold axis. Two precursors in the synthesis of (IV), namely 2,2'-bis(allyloxy)-5,5'-di-tert-butyl-3,3'-methanediyldibenzenemethanol (C(29)H(40)O(4)) and 2,2'-bis(allyloxy)-5,5'-di-tert-butyl-3,3'-methanediyldibenzaldehyde (C(29)H(36)O(4)) have also been characterized.
