Die Kristallstruktur von Bis(p‐chlorphenyl)cyclopropenon – eine Berichtigung

Crystal Structure of Bis(p-chlorophenyl)cyclopropenone – A Correction A crystal structure reinvestigation of the title compound led to bond distances within the expected ranges and similar to those observed in comparable compounds. The CC bond length opposite to the CO group in the three-membered ring is shorter than the two others (136.8 pm/141.8 pm). Significant deformations in the phenyl ring as well as other details demonstrate the conjugation in this system. – Our determination of 1973 resulted from an incorrect data set, probably influenced by systematic errors and the sensitivity of the compound to X-rays.
