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.
5,5'-二叔丁基-2,2'-二羟基-3,3'-亚甲基二苯甲醛（C₂₃H₂₈O₄，化合物IV）具有两种多晶型结构。四方晶型（空间群I4₁/a）先前已有报道，但在此重新测定并重新解释，而单斜晶型（空间群C2/c）则是首次报道。在这两种多晶型中，分子都位于一个晶体学二重轴上。化合物IV合成过程中的两种前体，即2,2'-双（烯丙氧基）-5,5'-二叔丁基-3,3'-亚甲基二苯甲醇（C₂₉H₄₀O₄）和2,2'-双（烯丙氧基）-5,5'-二叔丁基-3,3'-亚甲基二苯甲醛（C₂₉H₃₆O₄）也已得到表征。
