Abstract
The title compound crystallizes in the triclinic system, space group P, a= 11.197(5), b= 12.207(8), c= 17.146(7)Å, α= 103.06(5), β= 98.20(6), γ= 91.08(3)°. The structure was refined to R 0.0686 for 4816 independent reflections (X-ray diffractometer data). The unit cell contains two conformers in the ratio 1 : 1, one of which has all three neopentyl groups on the same side of the benzene ring, while the other has two on one side and one on the other. Indications for the operation of inter- and intra-molecular attractive steric effects are discussed.Keywords
