Abstract
The crystal structure of the fully substituted benzene compound, trimethyl-[2,4,6-tri(l ,1 -dimethylethyl)benzene] 1,3,5-tricarboxylate C 2 4 H 3 6 0 6 has been determined at 298 Κ and refined to R = 0.054 for 2201 observed reflections. Crystals are monoclinic, space group P2l/n with Ζ = 4 in a cell of dimensions a = 10.910(4), b = 22.186(8), c = 10.518(3) Ä and β = 115.58(2)°. The benzene ring is nonplanar while the angles about the ring are also distorted, [mean 122.1(3)° and 116.0(3)° about the ester and f-butyl groups respectively].
