Three different N-donors L, namely N-ethyl-N′-3-pyridyl-imidazolidine-4,5-dione-2-thione (1), N,N′-bis(3-pyridylmethyl)-imidazolidine-4,5-dione-2-thione (2), and tetra-2-pyridyl-pyrazine (3), bearing one, two and four pyridyl substituents, respectively, have been reacted with halogens X2 (X = Br, I) or interhalogens XY (X = I; Y = Cl, Br). CT σ-adducts L · nXY, bearing linear N?XY moieties (L = 3; X = I; Y = Br, I; n = 2), and salts containing the protonated cationic donors HnLn+ (L = 1 − 3; n = 1, 2, 4), counterbalanced by Cl−, Br−, , , , , I2Br−, , or anions, have been isolated. Among the reactions products, (H1+)Cl−, (H1+)Br−, , , and 3 · 2IBr have been characterised by single-crystal X-ray diffraction. The nature of the products has been elucidated based on elemental analysis and FT-Raman spectroscopy supported by MP2 and DFT calculations. 相似文献

Consideration of the non equivalence of hydrogen atoms in a methyl group attached to a planar moiety indicates that a component of electric dipole moment should exist in a direction perpendicular to the local C
3 axis of the CH3 group. Semiempirical molecular-orbital computations produced estimates of this moment and of the barriers to internal rotation which may make this moment observable. 相似文献

In the continuation of a review of the classification, properties and applications of mesophases, the general features of thermodynamic data of thermotropic liquid–crystalline phase transitions are surveyed. The orientation of molecules in liquid–crystalline mesophases is discussed in relation to the electrical properties. Some applications of mesophases are outlined. After surveys of both the structural classes of lyotropic mesophases and the properties of plastic crystals in cubic phases, the thermodynamic, structural and other properties of all mesophases-are summarily considered in relation to the present state of the knowledge in this field. 相似文献
