M. Bolte

Abstract: A new polymorph of the title compound, C₄₂H₃₆O₄, is reported. It crystallizes in space group P2₁/c, whereas the previously known polymorph [Bolte & Sakhaii (2004), Acta Cryst. C60, o1360-o1361] crystallizes in space group P $\\overline{1}$ . The conformations of the molecules differ in the orientation of one benzyl residue.
