Abstract
C6H604, Mr 142, triclinic, Pi , a=4.842(1), b=7.607(1), c=9.168 (3) Å , α=98.41 (2), β=99.89 (2), γ=77.74 (1)° , V=320.9 Å3, Z=2, Dm=1.45 (flotation), Dx=1.470 g cm -3, μ(Mo Kα, Λ=0.7107 Å) 0.63 cm-1, F(000)=148. The structure was solved by direct methods and refined to an R value of 0.038 for 723 intensity measurements. The geometrical changes in the cyclopropane ring are discussed in the light of substituent effects. In the crystal structure the carboxylic groups are disordered.
