MOLECULAR AND CRYSTAL STRUCTURE OF THE METHYL ESTER OF 2-CHLOROMERCURI-3-TRIFLUOROACETOXY-2,3-DIPHENYLCYCLOPROPANE-1-CARBOXYLIC ACID

Article abstract of DOI:10.1007/BF00752057

The crystal structure was determined for the methyl ester of 2-chloromercuri-3-trifluoroacetoxy-2,3-diphenylcyclopropane-1-carboxylic acid using a diffractometer, λMoK_α radiation, and θ/2θ scanning with 2θ_max = 60 deg to R = 0.058.The unit cell parameters for the monoclinic crystals are as follows: a = 17.595(2), b = 11.0454(9), c = 20.933(1) Angstroem, β = 97.281(8) deg, V = 4035.4(7) Angstroem³, Z = 8, space group p2₁/c.The HgCl, CO2Me, and CO2CF3 substituents in both independent molecules (A and B) are located on one side of the plane of the cyclopropane ring, while the phenyl groups are on the other side.All the bond lengths in this molecule are ordinary.
