Synthesis and X-Ray Crystal Structure of a New Potent Pyrethroid Acid, (+/-)-cis-3--2,2-dimethylcyclopropanecarboxylic Acid

Single-crystal X-ray analysis of the title compound has established its structure and molecular geometry.Crystals are monoclinic, space group P21/c, with a = 9.487(4), b = 8.009(4), c = 16.214(6) Angstroem, β = 119.91(1) deg, Z = 4.The structure was solved by direct methods and refined by full-matrix least-squares calculations to R 0.056 over 1242 reflections measured by diffractometer.The crystals contain centrosymmetric hydrogen-bonded dimers (O...O 2.65 Angstroem) in which the carboxy and vinyl substituents are in a 'bisecting' orientation, and the C=O group and one of hydrogen atoms on each methyl group point over the cyclopropane ring.The bond lengths in the ring reflect the substitution pattern.
