Autor: Olga E. Grikina, Leonid S. Khaikin, Marit Trætteberg, A. De Meijere, S. I. Kozhushkov

Publikováno v: Journal of Molecular Structure. 641:41-60

The molecular structure of 1,1-bis(trimethylsilylethynyl)cyclopropane has been studied by the gas electron diffraction method, by vibrational spectroscopic methods and by ab initio calculations at the RHF and MP2 levels. A scaled quantum-chemical for

Crystal structure of 5-oxatricyclo[5.1.0.01,3]octane-4-one: two polymorphs in one crystal

Autor: S. I. Kozhushkov, Judith A. K. Howard, A. De Meijere, Dmitrii S. Yufit

Publikováno v: Acta Crystallographica Section B Structural Science. 58:673-676

Two subsets of data, corresponding to different crystalline modifications of the title compound, 5-oxatricyclo[5.1.0.01,3]octane-4-one (C7H8O2), have been obtained from the same experiment. Both structures were successfully solved and refined. The pa

Spiro[4.4]nonatetraene and its Positive and Negative Radical Ions: Molectronic Structure Investigations

Autor: Edwin Haselbach, Anne-Christelle Sergenton, Armin de Meijere, Manuel Piacenza, Thomas Bally, Stefan Grimme, S. I. Kozhushkov, Michael Allan, Pawel Bednarek

Publikováno v: Helvetica Chimica Acta. 84:1670-1693

The electronic structure of spiro[4.4]nonatetraene 1 as well as that of its radical anion and cation were studied by different spectroscopies. The electron-energy-loss spectrum in the gas phase revealed the lowest triplet state at 2.98 eV and a group

Geometry of three-membered rings in triangulanes: an X-ray structural study and additivity scheme for carbon–carbon bond lengths in triangulanes

Autor: N. S. Zefirov, D. S. Yufit, K. A. Lukin, Yu. T. Struchkov, S. I. Kozhushkov

Publikováno v: Acta Crystallographica Section B Structural Science. 49:704-708

An X-ray structural study of two gem-dihalosubstituted triangulanes, possessing linear fragments of spiroannulated cyclopropanes, allowed us to work out an empirical calculation scheme describing the geometry of triangulanes. The crystal data for 1,1
