1,4-Bis(triphenylmethoxy)-2-butyne, Rhombohedral withZ' = 7/6

Abstract

The title compound, C42H34O2, crystallizes in the space group R\overline{3} with one molecule disordered at a crystallographic \overline{3} site and another in a general position. The conformation of the linkage of the trityl groups to the central butyne group is such that the O—C⋯C—O grouping forms a torsion angle of magnitude 87.2 (2)°. The C C distance length in the ordered molecule is 1.176 (3) Å.
