Polymorphism of triphenylantimony(V) bis-cumylperoxide
Two polymorphs of triphenylantimony(V) bis-cumylperoxide were obtained by the interaction of triphenylantimony(V) dihalides with cumene hydroperoxide in an aromatic hydrocarbon in the presence of ammonia or aqueous potassium hydroxide solution. The structure of two polymorphic modifications I and II was determined by the single crystal X-ray diffraction analysis, revealing the crystallization in monoclinic P21/n and P21/c space groups, respectively, with Z = 4. To our knowledge, this is the first report of polymorphism of peroxo complexes. The polymorph I was characterized by elemental and thermal analyses, Fourier transform infrared and Raman spectroscopies, and powder X-ray diffraction. Analysis of crystal structure databases revealed the similarity between peroxide, hydroperoxide, and organoperoxide ligands in the corresponding p-block element complexes.
期刊介绍：
Structural Chemistry is an international forum for the publication of peer-reviewed original research papers that cover the condensed and gaseous states of matter and involve numerous techniques for the determination of structure and energetics, their results, and the conclusions derived from these studies. The journal overcomes the unnatural separation in the current literature among the areas of structure determination, energetics, and applications, as well as builds a bridge to other chemical disciplines. Ist comprehensive coverage encompasses broad discussion of results, observation of relationships among various properties, and the description and application of structure and energy information in all domains of chemistry.
We welcome the broadest range of accounts of research in structural chemistry involving the discussion of methodologies and structures,experimental, theoretical, and computational, and their combinations. We encourage discussions of structural information collected for their chemicaland biological significance.
