Crystals of 1, 2‐ trans ‐cyclooctane‐dicarboxylic acid are monoclinic, a = 14.76 Å, b = 11.89 Å, c = 12.98 Å, β = 111.25°, space group C/2c with 8 molecules in the unit cell. The structure has been solved by direct methods and refined by full‐matrix least squares analysis of three‐dimensional intensity data. The cyclooctane ring is found to occur in an approximately mirror‐symmetric (‘boat‐chair’) conformation.
