Abstract
The title compound crystallises with two independent molecules in the asymmetric unit; monoclinic space group P21/n with a = 10.063(8), b = 23.015(15) and c = 12.938(10) Å β = 111.42(6)°, V = 2789(4) Å3 and Z = 8. Steric compression between the two methyl groups and the adjacent bay region hydrogens distorts the molecules from planarity and imparts handedness. The space group is centrosymmetric and the lattice is therefore racemic.
