Solid State Chemistry of Organic Polyvalent Iodine Compounds. IV. Topotactic Transformations of 2-Iodo-3'-Chlorodibenzoyl Peroxide and the Crystal Structure of m-Chlorobenzoic Acid.

摘要

Single crystals of 2-iodo-3'-chlorodibenzoyl peroxide (P) undergo several competitive and consecutive topotactic transformations: upon standing in the laboratory atmosphere or during X-ray photography at approx. 22 C, crystalline P is transformed to pseudomorphs containing preferentially oriented single crystal phases of o-iodosobenzoic acid (e), m-chlorobenzoic acid (D), and an as yet unidentified novel phase, 'X'.
