Molecular and crystal structure of diperoxides: X-ray diffraction studies of 2,5-dimethyl-2,5-dihydroperoxyhexane, 2,5-dimethyl-2,5-dihydroperoxyhex-3-ine, 2,5-dimethyl-2,5-di(tert-butylperoxy)hexane, and 1,4-bis[2-(2-tert-butylperoxy)propyl]benzene

The crystal structures of two alkylhydrodiperoxides and two dialkyldiperoxides, namely, 2,5-dimethyl-2,5-dihydroperoxyhexane (I), 2,5-dimethyl-2,5-dihydroperoxyhex-3-ine (II), 2,5-dimethyl-2,5-di(tert-butylperoxy) hexane (III), and 1,4-bis[2-(2-tert-butylperoxy)propyl]benzene (IV), are studied by X-ray diffraction. The structures of I–IV are compared with previously studied structures of alkylhydroperoxides, dialkylhydroperoxides, and their S, Se, and Te analogues, such as bis(alkyl)disulfides, bis(alkyl)diselenides, and bis(alkyl)ditellurides. The factors responsible for the structure of compounds of this type are analyzed, and the specific structural features are discussed.
